(1) This registration statement relates to securities of the registrant issuable
    to  DiviCom  Inc.,  a  Delaware  corporation  ("DiviCom"),  in  the proposed
    acquisition of DiviCom by registrant.
 
(2) There is no established trading market  for the shares of DiviCom which  are
    to  be converted  into cash  and shares  of Common  Stock of  the registrant
    pursuant to the Merger described  herein. In accordance with Rule  457(f)(2)
    under  the Securities  Act of  1933, given  that DiviCom  has an accumulated
    capital deficit,  the Proposed  Maximum Aggregate  Offering Price  has  been
    calculated  on the basis of one-third of the par value of the DiviCom shares
    less the $70,000,000 cash consideration to be paid by the registrant to  the
    holders  of the DiviCom  shares in connection with  the Merger. One-third of
    such par value  was $11,983 on  June 21, 1996,  the most recent  practicable
    date for determination.
 
(3) In  accordance  with  Section 6(b)  under  the Securities  Act of  1933, the
    registration fee  is  set  at  the  minimum  amount  for  the  filing  of  a
    registration statement. Such fee has been paid previously.

DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL
FILE A  FURTHER  AMENDMENT  WHICH SPECIFICALLY  STATES  THAT  THIS  REGISTRATION
STATEMENT  SHALL THEREAFTER BECOME EFFECTIVE IN  ACCORDANCE WITH SECTION 8(A) OF
THE SECURITIES ACT  OF 1933  OR UNTIL  THE REGISTRATION  STATEMENT SHALL  BECOME
EFFECTIVE  ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID SECTION 8(A),

                                                                   July   , 1996
 
Dear Stockholder:
 
    A  special meeting of stockholders of  DiviCom Inc. ("DiviCom") will be held
on July   , 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
the amendment  of  DiviCom's  Certificate  of  Incorporation  (the  "Certificate
Amendment").
 
    As  a result of the Merger, all  outstanding vested shares of DiviCom Common
Stock and 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 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  and 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.  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 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

                                OF STOCKHOLDERS

"DiviCom Meeting").
 
    At the DiviCom Meeting, DiviCom stockholders  will be asked to consider  and
vote  upon  a  proposal to  (i)  ensure that  the  Merger  is not  treated  as a
liquidation for which the holders of Preferred Stock will receive a  liquidation

Stock to buy certain DiviCom technology  for $1.00 on a DiviCom dissolution  and
other  DiviCom assets at  fair market value, (iii)  delete the preemptive rights
provision contained in DiviCom's  Certificate of Incorporation (such  amendments
collectively  constitute the "Certificate Amendment") and (iv) approve and adopt
the Agreement and Plan  of Reorganization and  Merger dated as  of May 28,  1996
(the "Reorganization Agreement"), entered into among C-Cube Microsystems Inc., a
Delaware   corporation   ("C-Cube"),  C-Cube   Acquisition  Corp.,   a  Delaware
corporation and a wholly owned subsidiary of C-Cube ("Merger Sub"), DiviCom  and
certain principal stockholders of DiviCom. The Reorganization Agreement provides
that  (i)  DiviCom will  be merged  with and  into Merger  Sub, with  Merger Sub
remaining as the surviving corporation and  a wholly owned subsidiary of  C-Cube
(the  "Merger");  (ii) each  outstanding vested  share  (I.E., those  shares not
subject to a right  of repurchase) of DiviCom  Preferred Stock and Common  Stock
(other  than shares dissenting from the Merger) will be converted into the right
to receive an amount of  cash equal to approximately $2.16  and a fraction of  a
share  of C-Cube Common  Stock equal to between  0.063720401 and 0.070801908 per
share depending  on the  average closing  price of  C-Cube 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
0.103811555  and 0.115348553 per share depending on the average closing price of
C-Cube Common  Stock  on the  twelve  (12) trading  days  prior to  the  DiviCom
meeting.  The Merger  is more  fully described  in the  Reorganization Agreement
attached as Annex A to the accompanying Prospectus/ Proxy Statement.
 
    Only stockholders of record at  the close of business on  July   , 1996  are
entitled  to  notice  of,  and  to  vote at,  the  DiviCom  Meeting,  or  at any
continuance(s)  or  adjournment(s)  thereof.   APPROVAL  AND  ADOPTION  OF   THE
REORGANIZATION  AGREEMENT AND THE CERTIFICATE AMENDMENT REQUIRES THE AFFIRMATIVE

                                         SHARES
                     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
2,610,412  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  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) 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),  and
(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. Assuming (x) that the  capitalization of DiviCom at the  Effective
Time  is in all respects  identical to the capitalization  of DiviCom at May 31,
1996 and  (y) a  closing date  of  August 20,  1996 (although  there can  be  no
assurance  as  to the  foregoing), each  share of  vested DiviCom  Capital Stock
exchanged  in  the  Merger  will  be   converted  into  the  right  to   receive
approximately  $2.16  in cash  and the  right  to receive  approximately between
0.063720401 and 0.070801908  of a share  of C-Cube Common  Stock. Each  unvested
share of DiviCom Common Stock exchanged in the Merger will be converted into the
right to receive approximately between 0.103811555 and 0.115348553 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 certain  holders 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  on July     , 1996  (the "DiviCom  Meeting"). This Prospectus/Proxy
Statement and  the accompanying  form of  proxy are  first being  mailed to  the

class,  and (ii) holders of  a two-thirds majority of  the outstanding shares of
DiviCom Preferred Stock, voting separately as a single class. SAGEM S.A.,  SAGEM

(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   % of the outstanding Common Stock  of
DiviCom.  The  SAGEM Entities  have  agreed to  vote  their shares  in  favor of
approval of the  Merger and  the Certificate  Amendment, as  have certain  other
affiliates  of DiviCom who hold,  collectively, an additional    % of the Common
Stock of DiviCom. In addition, C-Cube and its affiliates hold 3.6% of the Series
A Preferred Stock and   % 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 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  2,610,412. 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 Capital 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 (a "vested share")
(other than shares held by a holder 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")  (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.
 
    All  vested DiviCom Capital Stock on the Closing Date will be converted into
C-Cube Common Stock at a rate  that will be between 0.063720401 and  0.070801908
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  14.1 shares of vested DiviCom Capital Stock). The actual exchange ratio will
depend on  the number  of vested  shares of  DiviCom Capital  Stock  outstanding
immediately prior
 
                                       4
<PAGE>
to the Effective Time. The exchange ratios given above assume the closing of the
Merger  takes place on August 20, 1996, although there can be no assurance as to
this assumption. 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 or below. The conversion ratio will  not
be adjusted further even if the C-Cube stock price for such period is lower than
$48.50.  The "Per-Share Cash Amount" will depend  on the number of vested shares
of DiviCom outstanding  immediately prior  to the Effective  Time. Assuming  the
Closing occurs on August 20, 1996 (although there can be no assurance as to this
assumption), the Per Share Cash Amount will be approximately $2.16.
 
    All  unvested DiviCom  Capital Stock  will be  converted into  C-Cube Common
Stock at a rate that will be  between 0.103811555 and 0.115348553 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 8.7  shares of  unvested  DiviCom
Capital  Stock. 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 and that the Average Price is
equal to $  ,  although there can be no  assurance as to these assumptions,  the
Vested Exchange Ratio will be   and the Unvested Exchange Ratio will be   .
 
    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 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.
 
                                       5
<PAGE>
    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 July   , 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 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 $51.20, the
midpoint of the possible range,  an aggregate of approximately 2,217,525  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 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.
 
    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 The First National Bank  of
Boston ("Bank of Boston"), 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. Except  in limited circumstances, 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.
 
    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
 
                                       6
<PAGE>
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    , 1996,  the closing price of  C-Cube Common Stock  as
reported  on Nasdaq  was $     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.  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 Bank  of Boston  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 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.
 
                                       7
<PAGE>
    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 to the  business of 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 2,046,217 shares  of
DiviCom   Common  Stock  and  20,723,855   shares  of  DiviCom  Preferred  Stock
representing   % and   % 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  certain other
affiliates of DiviCom, 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, as
amended, and  accordingly  (i)  none  of 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. All DiviCom stockholders  should consult their  own tax advisors.  See
"The   Merger   and  Related   Transactions  --   Certain  Federal   Income  Tax
Considerations."
 
                                       8
<PAGE>
    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 technology  ownership between DiviCom and the  SAGEM
Entities, 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. 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."
 
    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  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

                                  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
 
                                       12
<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.
 
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, there will be no  adjustment to the number of shares  of
C-Cube  Common Stock  to be  issued in  the Merger  should the  Average Price of
C-Cube  Common  Stock  drop  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 and on July    , 1996, the  closing
price  of the C-Cube Common Stock was $     . 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
 
                                       13
<PAGE>
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 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 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
 
                                       14
<PAGE>
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
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,
 
                                       15
<PAGE>
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 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 and is in the process of  qualifying
additional  foundries including Samsung Semiconductor, Inc. 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  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
 
                                       17
<PAGE>
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 Divi-Com'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,  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
 
                                       18
<PAGE>
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, 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,  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 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
 
                                       19
<PAGE>
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.  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 is  in  the process  of  securing additional
foundry capacity in the  Republic of China  (Taiwan). 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.

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 HISTORY OF C-CUBE PROFITABILITY
 
    C-Cube  was organized in 1988 and  first achieved profitability in the third
quarter of 1993. At March 31, 1996,  C-Cube had retained earnings of only  $16.0
million  and,  on a  pro forma  basis, the  Combined Company  would have  had an
accumulated deficit of  $155.0 million  at March  31, 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.

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 have  certain other affiliates of DiviCom who  own
collectively  as of the  DiviCom Record Date  an additional     %  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."

                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  Merger  will  allow  the
     Combined  Company to more effectively  promote standards-based solutions 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.
 
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.
 
                                       24
<PAGE>
    -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.
 
    -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   AND   RESTRICTIONS   ON   DOING
      BUSINESS.  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, eliminate certain  business restrictions and reduce
      obligations relating to the development and transfer of DiviCom technology
      as embodied in the  Transition Agreement. These  agreements enable a  more
      favorable   allocation  of   the  Merger  consideration   to  the  DiviCom
      stockholders (other than the SAGEM Entities) and 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
 
    DiviCom's Board  of Directors  considered a  variety of  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
 
                                       25
<PAGE>
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, among other things: (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; (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 a variety of  potentially
negative  factors in its  deliberations concerning the  Merger, including, among
other things: (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  adversely  affected by  these  or other
factors; (iv) the risk  that the benefits  sought to be  achieved by the  Merger
will not be achieved; and (v) other risks described above under "Risk Factors."
 
    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, met  with Mr.  Nolan Daines, who  would later  become the President,
Chief Executive Officer, Chief Financial Officer  and a director of DiviCom,  on
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
 
                                       26
<PAGE>
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 close
relationship between C-Cube and DiviCom occurred intermittently after that date,
and 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.
 
    From  February 16, 1996 through March 31, 1996, C-Cube conducted preliminary
due diligence  on DiviCom,  and  certain members  of  management of  C-Cube  and
DiviCom met to discuss a possible merger.
 
    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, 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.
 
    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,
representatives  of DiviCom,  C-Cube and  certain of  the SAGEM  Entities 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  representatives of DiviCom, C-Cube
and certain of the SAGEM  Entities met in New York,  New York, to negotiate  the
remaining  unresolved issues pertaining to  the Merger, which primarily involved
the drafting and discussion of the Transition Agreement and finalizing the other
transaction documents.
 
                                       27
<PAGE>
    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 July   , 1996, or on a date as soon as
practicable thereafter.
 
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
2,558,797.  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)  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) 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.
 
        The "Vested Exchange Ratio" means the quotient obtained in the following
    manner: (a) calculate the quotient obtained by dividing the Aggregate  Share
    Number  (as defined below)  by 35,750,000; (b) (1)  calculate the product of
    Total Vested  Shares  Outstanding (as  defined  below) multiplied  by  $1.96
    ($70,000,000  divided by  35,750,000) and  round the  result to  the nearest
    dollar; (2) subtract the figure  obtained from (b)(1) from $70,000,000,  and
    if  the result is zero or is  negative, the quotient obtained from (a) above
    is the Vested Exchange Ratio, but if such quotient
 
                                       29
<PAGE>
    is a positive number, proceed; (3) divide the number obtained from (b)(2) by
    the Average Price  (as defined below)  and round the  result to the  nearest
    share;  (c) divide  the number obtained  from (b)(3) by  Total Vested Shares
    Outstanding; and (d) subtract the number  obtained from (c) from the  number
    obtained from (a). The Vested Exchange Ratio will not exceed 0.074976559.
 
        The  "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 Common  Stock on  the
    Nasdaq  National  Market,  or  the  national  securities  exchange  on which
    C-Cube's Common Stock is  then traded, for the  12 trading days  immediately
    preceding  the date of the DiviCom  Meeting (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. The Vested 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.
 
        The "Unvested Exchange  Ratio" means the  quotient obtained by  dividing
    the  Aggregate  Share Number  by 35,750,000  and  multiplying the  result by
    1.538461538 (or  $200 million  divided by  $130 million).  Depending on  the
    Average  Price, the Unvested  Exchange Ratio will  range between 0.103811555
    and 0.115348553.
 
        "Total Vested  Shares  Outstanding"  means  all  outstanding  shares  of
    DiviCom  Capital Stock  not subject  to a  repurchase right  at the original
    purchase price at the Effective Time.
 
        The "Per-Share  Cash Amount"  means the  quotient obtained  by  dividing
    $70,000,000  by  the  number  of  Vested  Shares  of  DiviCom  Capital Stock
    outstanding immediately prior to the Effective Time, rounded to the  nearest
    whole cent.
 
        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.
 
                                       30
<PAGE>
        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 July    , 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.
 
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 $51.20, the  midpoint of the possible  range
(the  "Exchange  Ratio Assumptions"),  an  aggregate of  approximately 2,217,525
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.
 
                                       31

    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 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 otherwise issuable to Significant Stockholders (the  "Escrow
Shares")  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.
 
    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

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

and Merger Sub shall have received a certificate to such effect signed on behalf
of  DiviCom by a duly authorized officer  of DiviCom; provided, however, that no
potential liability shall  accrue to the  extent representations and  warranties
are  untrue or inaccurate as a result of actions taken (i) by C-Cube, or (ii) by
DiviCom at  the direction  of, or  with the  prior written  consent of,  C-Cube,
during  the period  from the  date of  the Reorganization  Agreement through the
Closing, (b) each  of the  parties identified  by DiviCom  as being  one of  its

in full force and  effect, (c) DiviCom shall  have performed or complied  (which

provided in  the Reorganization  Agreement) in  all material  respects with  all
agreements  and  covenants  required  by  the  Reorganization  Agreement  to  be
performed or complied with by it on  or prior to the Effective Time; and  C-Cube
and Merger Sub shall have received a certificate to such effect signed by a duly
authorized  officer  of  DiviCom,  (d) C-Cube  shall  have  been  furnished with
evidence satisfactory to  it that  DiviCom has obtained  the material  consents,
approvals  and waivers  set forth  in the  Reorganization Agreement,  (e) C-Cube

and  all such noncompetition  agreements shall remain in  full force and effect,
(h) holders  of more  than five  percent of  the outstanding  shares of  DiviCom
Capital  Stock shall not have exercised, nor shall they have any continued right
to exercise, appraisal, dissenters' or similar rights under applicable law  with
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
 
                                       36
<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 a part: (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.
 
                                       37
<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  certain other affiliates  of
DiviCom, have 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, which is irrevocable, 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.
 
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
 
                                       38
<PAGE>
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 may forgive  the 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.
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. As part of the Transition Agreement, that  will
be  effective upon the Closing of the Merger. 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.  This discussion  does  not  deal with  all  income tax
considerations that may be relevant to particular DiviCom stockholders in  light
of  their  particular circumstances,  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.
 
                                       39
<PAGE>
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 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
 
                                       40
<PAGE>
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.  DiviCom and  C-Cube will receive  opinions from  their respective legal
counsel, 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 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.
 
                                       41
<PAGE>
    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 FEDERAL
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 $170.4  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.
 
    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
 
                                       42
<PAGE>
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 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  March  31, 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 $195.7 million has been calculated based
on  the assumption that  C-Cube's stock price  is within the  range of $53.89 to
$48.50 as defined  in the Reorganization  Agreement 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 2.2  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 $15 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
$51.20  per share, which is  the mid-point of the  maximum share price of $53.89
and the  minimum  share  price  of  $48.50  as  defined  in  the  Reorganization
Agreement.  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 $183.1 million to purchased technology, $170.4
million of which represented in-process research and development.
 
    The  unaudited pro forma condensed combined statements of operations for the
year ended December  31, 1995  and for  the quarter  ended March  31, 1996  give
effect  to  the proposed  merger  as if  the  acquisition was  completed  at the
beginning of  the year  and  quarter, 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 $170.4 million nonrecurring charge for in-process
research and development. However such statements do reflect adjustments for the
elimination  of  transactions  between  C-Cube  and  DiviCom,  amortization   of
purchased  technology, 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.

                         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
 
                                       49
<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.

    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.
 
                                       51
<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.
 
                                       52
<PAGE>
    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.

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.

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
 
                                       57
<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 March 31, 1996, the Company had
169 full-time employees  engaged in research  and development. Expenditures  for
research  and development for the first quarter  of 1996 and during fiscal years
1995, 1994 and 1993 were approximately $6.9 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
 
                                       58
<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  quarter of  1996 and during  fiscal years  1995, 1994 and
1993, international revenues accounted for  approximately 76%, 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
 
                                       59
<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
 
                                       60
<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.
 
                                       61
<PAGE>
    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  the principal factors  of competition in  its markets  are
product  definition, product design, system cost, functionality, time-to-market,
reliability and reputation. C-Cube believes  it competes favorably with  respect
to  most of these factors. 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.
 
                                       62
<PAGE>
    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.

    C-Cube attempts to protect its technology through a combination of  patents,
copyrights,   trade  secret  laws,   confidentiality  procedures  and  licensing
arrangements. As of March  31, 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,
 
                                       63
<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 370 employees, 203 of whom are
engaged in, or directly support, C-Cube's  research and development, 92 of  whom
are  in sales and marketing, 36 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.
 
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 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.

                         INFORMATION CONCERNING DIVICOM
 
    DiviCom  Inc. ("DiviCom"),  incorporated in Delaware  in 1993,  is a leading
supplier of MPEG 2-based systems, subsystems  and components that are a part  of
the  emerging  worldwide  digital  video  infrastructure.  DiviCom  develops and
integrates products and systems that  transmit and receive digital video,  audio
and  data over networks allowing its customers to create integrated "end-to-end"
digital  video  networks.  DiviCom  is  focused  on  merging  video  and   audio
compression  technologies  with  network  and  communications  technologies into
innovative products  for  producers, distributors  and  consumers of  video  and
video-enhanced  information.  Products  include  Moving  Pictures  Experts Group
("MPEG") audio/video  encoders,  networking and  decoding  systems, as  well  as
integration services through its DiviSys Integration Group. Based on the MPEG 2,
Digital  Video  Broadcasting  ("DVB")  and  Asynchronous  Transfer  Mode ("ATM")
international standards, DiviCom's  products enable  digital video  broadcasting
over  a variety of digital video  networks, including Direct Broadcast Satellite
("DBS"), wireless  cable, also  known  as Multichannel  Multipoint  Distribution
Systems  ("MMDS"), and wired services,  including Switched Digital Video ("SDV")
services, digital cable, or  Hybrid Fiber Coax ("HFC")  and copper twisted  pair
wiring referred to as Asynchronous Digital Subscriber Line ("ADSL").
 
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
 
                                       67
<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.

    SYSTEMS PRODUCTS
 
    Systems  products  offerings  consist  of  encoders,  multiplexers,   system
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

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
 
                                       68

    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
 
                                       70
<PAGE>
for  consumer  electronics  products  and as  a  consequence,  any  political or
economic instability in  such 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 March  31, 1996, DiviCom had over 80 employees
engaged in research and development.
 
    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 competes on  the
basis  of focus and technology leadership in digital video networking as well as
technology and services to provide systemization of its products.
 
    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
 
                                       72
<PAGE>
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  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 March 31, 1996, DiviCom had a total of 159 employees, of whom 81  were
engaged  in  research  and  development,  17  in  sales  and  marketing,  16  in
professional services  and  technical  support,  26  in  operations  and  19  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.
 
FACILITIES
 
    DiviCom's corporate headquarters occupy an aggregate of approximately 46,000
square  feet in  Milpitas, California,  under a  lease that  expires in February
1999. DiviCom's  Development,  Administrative, Sales,  Marketing,  and  Customer
Support functions are located at this location. DiviCom's

           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 quarter 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  royalty
revenues  on services and  technology, including advanced  MPEG 2 technology for
settop box and consumer product applications. In January 1996, DiviCom  launched
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.
 
RESULTS OF OPERATIONS

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.
 
                                       76
<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 THREE MONTHS ENDED MARCH, 31 1995 AND MARCH 31, 1996
 
    NET REVENUES
 
    Net Revenues increased 31% to $10.2 million for the first quarter of 1996 as
compared to  $7.8  million  for the  first  quarter  of 1995  due  to  increased
shipments  of DiviCom's encoder products. For  the three months ending March 31,
1996, Thomson, Tele-TV and the SAGEM Entities accounted for 29%, 11% and 11%  of
net revenues, respectively.
 
    GROSS MARGIN
 
    Gross  margin as  a percentage  of net  revenues was  52% and  43% for three
months ending March 31, 1996 and March 31, 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 declined  to $3.1 million  for the  first
quarter  of 1996, as compared to $3.3 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  for  first
quarter  of 1995 charges  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 $1.8 million in the  first
quarter  of 1996 compared to $1.0 million in the first quarter of 1995. Selling,
general and  administrative expenses  increased due  to increased  staffing  and
related  expenses  and higher  sales commissions  associated with  increased net
revenues.
 
                                       77
<PAGE>
    INTEREST INCOME (EXPENSE), NET
 
    Interest income increased to $91,000 for the first quarter of 1996  compared
to  $25,000 for the  first quarter 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  quarter  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
March  31, 1996, DiviCom had received $17.1 million from development funding and
$12.1 million from the sale of  equity securities. At March 31, 1996,  DiviCom's
current  sources of liquidity included cash and cash equivalents of $9.4 million
and a  bank  line of  credit  in the  amount  of $15  million.  Working  capital
increased  to $11.1 million at March 31, 1996 from $10.6 million at December 31,
1995 principally as a result of first quarter cash from operations.
 
    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  provided cash of $2.3 million
in the  first quarter  of 1996  primarily from  increased deferred  revenue  and
accounts   payable  partially  offset  by   increased  accounts  receivable  and
inventory.
 
    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 $1.4
million in  the  first  quarter  of 1996  primarily  to  purchase  property  and
equipment.   DiviCom's  financing  activities  provided  cash  of  $1.1  million
primarily from receipt of 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.

(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.
 
(3) All 150,000 shares received are restricted and subject to the repurchase  at
    original cost by DiviCom as the options were not yet vested as of the end of

stock are fully vested. In addition, the Transition Agreement provides that  any

    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.
 
                                       84

    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.
 
    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.
 
    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.
 
    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  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 vested  shares of DiviCom
Capital Stock will receive  cash and shares of  C-Cube Common Stock in  exchange
for  their vested  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 over the affairs of C-Cube than currently enjoyed  over
the affairs of DiviCom.

                       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.

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.

</TABLE>
 
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
reserved for conversion of preferred stock.
 
    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.

5.  STOCKHOLDERS' EQUITY: (CONTINUED)
 
    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:

    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

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 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.

    The difference  between the  Company's  effective income  tax rate  and  the

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.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
    This  AGREEMENT AND  PLAN OF REORGANIZATION  (this "AGREEMENT")  is made and
entered into  as of  May 28,  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
repre-sentations  and  warranties and  other agreements  in connection  with the
Merger.
 
    NOW,  THEREFORE,   in  consideration   of   the  covenants,   promises   and
representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby, the parties agree as follows:
 
                                   ARTICLE I
                                   THE MERGER
 
    1.1   THE  MERGER.  At  the Effective Time  (as defined in  Section 1.2) and
subject toand upon the terms and conditions of this Agreement and the applicable
provisions of the Delaware General Corporation Law ("DELAWARE LAW"), the Company
shall be merged with  and into Merger Sub,  the separate corporate existence  of
the  Company  shall  cease  and  Merger  Sub  shall  continue  as  the surviving
corporation and  as a  wholly-owned  subsidiary of  Parent.  Merger Sub  as  the
surviving  corporation after the Merger is  hereinafter sometimes referred to as
the "SURVIVING CORPORATION."
 
    1.2  EFFECTIVE TIME.  Unless  this Agreement is earlier terminated  pursuant
to  Section 8.1, the  closing of the  Merger (the "CLOSING")  will take place as
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
of Wilson Sonsini  Goodrich &  Rosati, Professional Corporation,  650 Page  Mill
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
limiting the generality of the foregoing, and subject thereto, at the  Effective
Time,  all  the  property,  rights, privileges,  powers  and  franchises  of the
<PAGE>
Company and Merger Sub shall vest  in the Surviving Corporation, and all  debts,
liabilities,  obligations and duties of the  Company and Merger Sub shall become
the debts, liabilities, obligations and duties of the Surviving Corporation.
 
    1.4  CERTIFICATE OF INCORPORATION; BYLAWS.
 
        (a) Unless otherwise determined by  Parent prior to the Effective  Time,
    at  the Effective Time, the Certificate of Incorporation of Merger Sub shall
    be the  Certificate  of Incorporation  of  the Surviving  Corporation  until
    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
    thereafter amended.
 
    1.5  DIRECTORS AND OFFICERS.  The directors of Merger Sub immediately  prior
to  the  Effective  Time  shall  be  the  initial  directors  of  the  Surviving
Corporation,  each  to  hold  office  in  accordance  with  the  Certificate  of
Incorporation  and  Bylaws of  the Surviving  Corporation.  The officers  of the
Company immediately prior to the Effective Time shall be the initial officers of
the Surviving Corporation, each to hold office in accordance with the Bylaws  of
the Surviving Corporation.
 
    1.6  MERGER CONSIDERATION; EFFECT ON CAPITAL STOCK.  The consideration to be
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:
 
        (a)   CONSIDERATION FOR  COMPANY  CAPITAL STOCK.    Upon the  terms  and
    subject  to the  conditions set forth  below and  throughout this Agreement,
    including, without limitation,  the escrow provisions  set forth in  Article
    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
       at which the Merger and the other
 
                                      A-3
<PAGE>
       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
       payment  to  holders of  unvested  Company Options  and  unvested Company
       Common Stock pursuant to the Unvested Exchange Ratio.
 
          (iii) "PER-SHARE CASH AMOUNT" means the quotient obtained by  dividing
       the  Aggregate  Cash Amount  by the  number of  vested shares  of Company
       Capital Stock  outstanding  immediately  prior  to  the  Effective  Time,
       rounded to the nearest whole cent.
 
          (iv) "TOTAL VESTED SHARES OUTSTANDING" means all outstanding shares of
       DiviCom  Capital  Stock not  subject to  a  repurchase right  at original
       purchase price at the Effective Time.
 
           (v) "VESTED  EXCHANGE  RATIO"  means the  quotient  obtained  in  the
       following manner:
 
               (a)  Calculate the  quotient obtained  by dividing  the Aggregate
           Share Number by 35,750,000.
 
               (b) (1)  Calculate the product of Total Vested Shares Outstanding
           multiplied by $1.96 (or $70,000,000 divided by 35,750,000) and  round
           the result to the nearest dollar.
 
                   (2)   Subtract (b)(1) from $70,000,000. If the result is zero
               or negative, use (a) above as the Vested Exchange Ratio.
 
                   (3)  Divide (b)(2) above by  the Average Price and round  the
               result  to the nearest share. (Note that the share price used may
               not be greater than $53.89 or less than $48.50.)
 
               (c) Divide (b)(3) above by Total Vested Shares Outstanding.
 
               (d) Subtract  (c)  above  from  (a) above.  This  is  the  Vested
           Exchange Ratio.
 
        Depending  on  the Average  Price, the  Vested  Exchange Ratio  will not
    exceed 0.074976559.
 
          (vi) "UNVESTED EXCHANGE RATIO" means the quotient obtained by dividing
       the Aggregate Share Number  by 35,750,000 and  multiplying the result  by
       1.538461538  (or $200 million divided by  $130 million). Depending on the
       Average Price, the Unvested Exchange Ratio will range between 0.103811555
       and 0.115348553.
 
    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
 
                                      A-4
<PAGE>
    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.
 
        (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 The First  National Bank  of Boston 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.
 
                                      A-5
<PAGE>
           (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  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,
 
                                      A-6
<PAGE>
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.
 
    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.
 
                                      A-7
<PAGE>
        (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 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
stockholders  to duly approve  the Merger and  this Agreement is  that number of
shares as  would constitute  (a) a  majority of  the outstanding  shares of  the
Common  Stock and Preferred Stock, voting together  as a single class (with each
share of Preferred Stock being entitled to a number of votes equal to the number
of whole shares of Common Stock into  which such share of Preferred Stock  could
be  converted on the  record date for the  vote), and (b)  two-thirds (b) of the
outstanding Preferred Stock voting separately  as a single class. The  execution
and  delivery  of  this  Agreement  and  the  consummation  of  the transactions
contemplated hereby have been duly authorized by all necessary corporate  action
on  the part of the Company,  subject only to the approval  of the Merger by the
Company's  stockholders.  The  Company's  Board  of  Directors  has  unanimously
approved  the Merger and  this Agreement. This Agreement  has been duly executed
and delivered by the Company and constitutes the valid and binding obligation of
the Company, enforceable in  accordance with its terms.  Except as set forth  on
Schedule  2.4, subject only to the approval  of the Merger and this Agreement by
the Company's stockholders, the execution and delivery of this Agreement by  the
Company  does  not, and,  as  of the  Effective  Time, the  consummation  of the
transactions contemplated  hereby will  not,  conflict with,  or result  in  any
material  violation of,  or material  default under  (with or  without notice or
lapse of time, or both), or give rise to a right of termination, cancellation or
acceleration of any obligation or loss  of any material benefit under (any  such
event,  a "CONFLICT") (i)  any provision of the  Certificate of Incorporation or
Bylaws of the Company or (ii) any material mortgage, indenture, lease,  contract
or  other  agreement  or  instrument,  permit,  concession,  franchise, license,
judgment, order, decree, statute, law, ordinance, rule or regulation  applicable

("GOVERNMENTAL  ENTITY") or any third party (so as not to trigger any Conflict),
is required by or with respect to  the Company in connection with the  execution
and  delivery  of  this  Agreement  or  the  consummation  of  the  transactions
contemplated hereby, except for (i) the filing of the Certificate of Merger with
the Delaware Secretary of State,

transactions  contemplated hereby and any  supplemental information requested in
connection therewith pursuant  to the  Hart-Scott-Rodino Antitrust  Improvements
Act  of 1976, as amended  (the "HSR Act"), with  the United States Federal Trade
Commission (the "FTC") and the United  States Department of Justice (the  "DOJ")
and compliance with the provisions of the HSR Act, (iii) such consents, waivers,
approvals,  orders, authorizations,  registrations, declarations  and filings as
may be required under applicable federal and state securities laws, (iv) such as
may be required solely by virtue of Parent's status and (v) such other consents,
waivers, authorizations,  filings, approvals  and  registrations which  are  set
forth on Schedule 2.4.
 
    2.5  COMPANY FINANCIAL STATEMENTS.
 
        (a) Schedule 2.5(a) sets forth the Company's audited balance sheet as of

    of  the Company as currently conducted or as proposed to be conducted by the
    Company as  of  the date  hereof  (collectively, the  "COMPANY  INTELLECTUAL
    PROPERTY  RIGHTS"). Following the Closing, the Company Intellectual Property
    Rights will have been transferred to Merger  Sub and Merger Sub will own  or

    therefor,  owned by, or  exclusively licensed to,  the Company (the "COMPANY
    REGISTERED INTELLECTUAL PROPERTY RIGHTS"), and specifies, where  applicable,
    the  jurisdictions  in  which  each  such  Company  Registered  Intellectual
    Property Right has been issued or registered or in which an application  for
    such  issuance  and registration  has been  filed, including  the respective

    user  licenses granted to end-users in  the ordinary course of business that
    permit use of  software products without  a right to  modify, distribute  or
    sublicense  the same ("End-User Licenses")) to  which the Company is a party

    respect  to  any patents,  copyrights,  trade secrets,  trademarks  or other
    proprietary rights of any third party or (ii) the Company has granted to any
    third party rights to any of  the Company Intellectual Property Rights,  and
    includes  the identity of all parties thereto. The execution and 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 Company  to

    have been transferred to Merger Sub and Merger Sub will be able to  exercise
    all  rights of the  Company under such  licenses, sublicenses and agreements
    without payment by any party or the Surviving Corporation of any  additional
    consideration.
 
        (c)  No claims with respect to  the Company Intellectual Property Rights
    have been asserted  or are, to  the Company's knowledge,  threatened by  any
    person,  nor are there any valid grounds for any bona fide claims (i) to the
    effect that the manufacture, sale, licensing  or use of any of the  products
    or  processes of the Company infringes on any copyright, patent, trade mark,
    service mark, trade secret or other proprietary right, (ii) against the  use
    by the Company of any trademarks, service marks, trade names, trade secrets,
    copyrights,  maskworks, patents,  technology, know-how  or computer software
    programs and  applications  used  in the  Company's  business  as  currently
    conducted  or  as  proposed  to  be  conducted  by  the  Company,  or  (iii)
    challenging the ownership by the  Company, or the validity or  effectiveness
    of   any  of  the  Company  Intellectual  Property  Rights.  All  registered
    trademarks, service marks and copyrights held  by the Company are valid  and
    subsisting. Except as set forth in Section 2.11(c) of the Disclosure Letter,
    the  business of the Company as currently conducted or as currently proposed
    to be  conducted  by the  Company  has not  and  does not  infringe  on  any
    proprietary  right of any third party.  To the Company's knowledge, there is
    no material unauthorized use, infringement or misappropriation of any of the
    Company Intellectual  Property  Rights by  any  third party,  including  any
    employee  or  former  employee of  the  Company  or any  stockholder  of the
    Company. No Company Intellectual Property Right or product of the Company or
    any of  its  subsidiaries  is  subject to  any  outstanding  decree,  order,
    judgment, or stipulation restricting in any manner the practice or licensing
    thereof  by  the Company.  Except as  set  forth in  Section 2.11(c)  of the

and  authority to enter  into this Agreement and  to consummate the transactions

constitutes the  valid  and  binding  obligations  of  Parent  and  Merger  Sub,
enforceable  in accordance  with its terms.  The execution and  delivery of this
Agreement by Parent does not, and, as of the Effective Time, the consummation of

of  the Certificate of Incorporation  or Bylaws of Parent,  or (ii) any material
mortgage, indenture, lease, contract or  other agreement or instrument,  permit,

ACT") for all periods subsequent to the year ended December 31, 1993, all in the
form  so filed (all of the foregoing  being collectively referred to as the "SEC
DOCUMENTS"). As of their respective filing dates, the SEC Documents complied  in

adjustments).  There has been no change  in Parent accounting policies except as
described in the notes to the Parent Financial Statements.
 
    3.6   NO MATERIAL  ADVERSE CHANGE.   Since  the date  of the  balance  sheet
included  in the Parent's most recently filed SEC Document, Parent has conducted
its business in the ordinary course and there has not occurred: (a) any material
adverse change in the  financial condition, liabilities,  assets or business  of
Parent;  (b) any amendment or change  in the Certificate of Incorporation (other
than to increase the authorized shares of Parent Common Stock from 50,000,000 to
150,000,000 shares) or Bylaws  of Parent; or (c)  any damage to, destruction  or
loss  of any assets  of the Parent,  (whether or not  covered by insurance) that
materially and adversely affects the financial condition or business of Parent.
 
    3.7  LITIGATION.  There is  no action, suit, proceeding, claim,  arbitration
or  investigation pending,  or as  to which  Parent has  received any  notice of
assertion against Parent  which in any  manner challenges or  seeks to  prevent,
enjoin,  alter or materially delay any  of the transactions contemplated by this
Agreement or that would have a  material adverse effect on the business,  assets
(including  intangible  assets), financial  condition,  prospects or  results of
operations of Parent and its subsidiaries, taken as whole.

stated therein or necessary to make the statements made therein, in light of the
circumstances in  which they  are made,  not misleading,  except to  the  extent
corrected  by  a  subsequently  filed  document  with  the  SEC.  The  financial
statements of Parent, including the notes thereto, included in the  Registration
Statement  will  comply as  to  form in  all  material respects  with applicable
accounting requirements and with the published rules and regulations of the  SEC
with  respect  thereto, will  have been  prepared  in accordance  with generally
accepted accounting principles consistently applied (except as may be  indicated
in  the  notes  thereto)  and will  present  fairly  the  consolidated financial
position of Parent at the dates thereof and of its operations and cash flows for
the periods then ended (subject, in the case of unaudited statements, to  normal
audit adjustments).

        (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

    stockholders to  the  Merger  and  the  transactions  contemplated  by  this
    Agreement  by  thirty  days after  the  effective date  of  the Registration

    Where action is taken to terminate  this Agreement pursuant to this  Section

hereto.

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

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

    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.
 
        (d)  LEGAL OPINION.  The Company and Seller shall have received a  legal
    opinion  from Wilson  Sonsini Goodrich  & Rosati,  Professional Corporation,
    legal counsel to Parent, covering  matters customarily addressed in  similar
    transactions  and in the form and substance reasonably acceptable to Company
    and Seller.
 
        (e)   MATERIAL  ADVERSE CHANGE.    There  shall not  have  occurred  any
    material  adverse  change  in  the  business,  assets  (including intangible
    assets), financial condition, prospects or  results of operations of  Parent
    since March 31, 1996.
 
        (f)   OTHER ADVERSE DEVELOPMENTS.  There shall not have occurred (i) any
    suspension or limitation of  trading in securities  generally on the  Nasdaq
    Stock  Market or any national securities exchange, or any setting of minimum
    prices for trading on any such  exchange or in the over-the-counter  market,
    (ii)  any imposition of  governmental restrictions on  trading in securities
    generally, (iii)  a  banking  moratorium either  by  Federal  or  California
    authorities, or (iv) an outbreak of major international hostilities or other
    national calamity in the United States.

                                  SECTION 262
                        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 Section228 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 Section251, 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 Section251 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
    SectionSection251,  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 Section228
    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.)

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.

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.
 
                                      II-2

    (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.

                      RESTATED CERTIFICATE OF INCORPORATION

                                       OF

                            C-CUBE MICROSYSTEMS INC.

  (Pursuant to Section 245 of General Corporation Law of the State of Delaware)

     C-Cube Microsystems Inc., a corporation organized and existing under the
General Corporation Law of the State of Delaware, which was originally
incorporated in Delaware under the name C-Cube Microsystems Delaware Corporation
on February 8, 1994, (the "Corporation") certifies as follows:

     1.   The Corporation's Restated Certificate of Incorporation was duly
adopted by the Board of Directors at a regular meeting in accordance with
Section 245 of the Corporation Law.

     2.   The Corporation's Restated Certificate of Incorporation only restates
and integrates and does not further amend the provisions of the Corporation's
Certificate of Incorporation as theretofore amended or supplemented, and there
is no discrepancy between those provisions and the provisions of the Restated
Certificate.

     3.   The Corporation's Certificate of Incorporation is restated to read in
full as follows:

     FIRST:    The name of the Corporation is C-Cube Microsystems Inc.

     SECOND:   The address of the registered office of the Corporation in the
               State of Delaware is Incorporating Services, Ltd., 15 East North
               Street, in the City of Dover, County of Kent. The name of the
               registered agent at that address is Incorporating Services, Ltd.

     THIRD:    The purpose of the Corporation is to engage in any lawful act or
               activity for which a corporation may be organized under the
               General Corporation Law of Delaware.

     FOURTH:

          A.   The total number of shares of all classes of stock which the
               Corporation shall have authority to issue is One Hundred Fifty
               Five Million (155,000,000), which consists of 150,000,000 shares
               of Common Stock with par value of $.001 per share and 5,000,000
               shares of Preferred Stock with par value of $.001 per share.

<PAGE>

          B.   The Preferred shares authorized by this Certificate of
               Incorporation may be issued from time to time in one or more
               series.  The Board of Directors is authorized 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 shares, and to fix, increase or decrease the
               number of shares comprising any such series and the designation
               thereof, or any of them, and to provide for the rights and terms
               of redemption or conversion of the shares of any such series.

     FIFTH:    The following provisions are inserted for the management of the
               business and the conduct of the affairs of the Corporation, and
               for further definition, limitation and regulation of the powers
               of the Corporation and of its directors and stockholders:

          A.   The business and affairs of the Corporation shall be managed by
               or under the direction of the Board of Directors.  In addition to
               the powers and authority expressly conferred upon them by statute
               or by this Certificate of Incorporation or the By-Laws of the
               Corporation, the directors are hereby empowered  to  exercise all
               such powers and do all such acts and things as may be exercised
               or done by the Corporation.

          B.   The directors of the Corporation need not be elected by written
               ballot unless the By-Laws so provide.

          C.   On and after the closing date of the first sale of the
               Corporation's Common Stock pursuant to a firmly underwritten
               registered public offering (the "IPO"), any action required or
               permitted to be taken by the stockholders of the Corporation must
               be effected at a duty called annual or special meeting of
               stockholders of the Corporation and may not be effected by any
               consent in writing by such stockholders.  Prior to such sale,
               unless otherwise provided by law, any action which may otherwise
               be taken at any meeting of the stockholders may be taken without
               a meeting and without prior notice, if a written consent
               describing such actions is signed by the holders of outstanding
               shares having not less than the minimum number of votes which
               would be  necessary to authorize or take such action at a meeting
               at which all shares entitled to vote thereon were present and
               voted.

          D.   Special meetings of stockholders of the Corporation may be called
               only (1) by the Board of Directors pursuant to a resolution
               adopted by a majority of the total number of authorized directors
               (whether or not there exist any vacancies in previously
               authorized directorships at the time any such resolution is
               presented to the Board for adoption) or (2) by the holders of not
               less than ten percent (10%) of all of the shares entitled to cast
               votes at the meeting.

     SIXTH:

          A.   The number of directors shall initially be eight (8) and,
               thereafter, shall be fixed from time to time exclusively by the
               Board of Directors pursuant to a resolution adopted by a majority
               of the total number of authorized directors (whether or not there
               exist any vacancies in previously  authorized directorships at
               the time any such resolution is presented to the Board for
               adoption).  After the closing of the IPO, the directors shall be
               divided into  three classes, with the term of office of the first
               class (Class I) to expire at the  first annual meeting of the
               stockholders following the IPO;  the term of office  of the
               second class (Class II) to expire at the second annual meeting of
               stockholders held following the IPO; the term of office of the
               third class (Class III) to expire at the third annual meeting of
               stockholders following the IPO; and thereafter for each such term
               to expire at each third succeeding annual meeting of stockholders
               after such election.  Subject to the rights of the holders of any
               series of Preferred Stock then outstanding, a vacancy resulting
               from the removal of a director by the stockholders as provided in
               Article SIXTH, Section C below may be filled at a special meeting
               of the stockholders held for that purpose.  All directors shall
               hold office until the expiration of the term for which elected,
               and until their respective successors are elected, except in the
               case of the death, resignation, or removal of any director.

          B.   Subject to the rights of the holders of any series of Preferred
               Stock then outstanding, newly created directorships resulting
               from any increase in the authorized number of directors or any
               vacancies in the Board of Directors resulting from death,
               resignation or other cause (other than removal from office by a
               vote of the stockholders) may be filled only by a majority vote
               of the directors then in office, though less than a quorum, and
               directors so chosen  shall hold office for a term expiring at the
               next annual meeting of stockholders at which the term of office
               of the class to which they have been elected expires, and until
               their respective successors are elected, except in the case of
               the death, resignation, or removal of any director. No decrease
               in the number of directors constituting the Board of Directors
               shall shorten the term of any incumbent director.

          C.   Subject to the rights of the holders of any series of Preferred
               Stock then outstanding, any directors, or the entire Board of
               Directors, may be removed  from office at any time, with or
               without cause, but only by the affirmative vote of the holders of
               at least a majority of the voting power of all of the then
               outstanding shares of capital stock of the Corporation entitled
               to vote generally in the election of directors, voting together
               as a single class.  Vacancies in the Board of Directors resulting
               from such removal may be filled by a majority of the directors
               then in office, though less than a quorum, or by the stockholders
               as provided in Article SIXTH, Section A above.  Directors so
               chosen shall


                                       -3-

<PAGE>

               hold office for a term expiring at the next annual meeting of
               stockholders at which the term of office of the class to which
               they have been elected expires, and until their respective
               successors are elected, except in the case of the death,
               resignation, or removal of any director.

     SEVENTH:  The Board of Directors is expressly empowered to adopt, amend or
               repeal By-Laws of the Corporation.  Any adoption, amendment or
               repeal of By-Laws of the Corporation by the Board of Directors
               shall require the approval of a majority of the total number of
               authorized directors (whether or not there exist any vacancies in
               previously authorized directorships at the time any resolution
               providing for adoption, amendment or repeal is presented to the
               Board).  The stockholders shall also have power to adopt, amend
               or repeal the By-Laws of the Corporation.  Any adoption,
               amendment or repeal of By-Laws of the Corporation by the
               stockholders shall require, in addition to any vote of the
               holders of any class or series of stock of the Corporation
               required by law or by this Certificate of Incorporation, the
               affirmative vote of the holders of at least sixty-six and two-
               thirds percent (66-2/3%) of the voting power of all of the then
               outstanding shares of the capital stock of the Corporation
               entitled to vote generally in the election of directors, voting
               together as a single class.

     EIGHTH:   A director of the Corporation shall not be personally liable to
               the Corporation or its stockholders for monetary damages for
               breach of fiduciary duty as a director, except for liability (i)
               for any breach of the director's duty of loyalty to the
               Corporation or its stockholders, (ii) for acts or omissions not
               in good faith or which involved intentional misconduct or a
               knowing violation of law, (iii) under Section 174 of the Delaware
               General Corporation Law, or (iv) for any transaction from which
               the director derived an improper personal benefit.

               If the Delaware General Corporation Law is hereafter amended to
               authorize the further elimination or limitation of the liability
               of a director, then the liability of a director of the
               Corporation shall be eliminated or limited to the fullest extent
               permitted by the Delaware General Corporation Law, as so amended.

               Any repeal or modification of the foregoing provisions of this
               Article EIGHTH by the stockholders of the Corporation shall not
               adversely affect any right or protection of a director of the
               Corporation existing at the time of such repeal or modification.

     NINTH:    The Corporation reserves the right to amend or repeal any
               provision contained in this Certificate of Incorporation in the
               manner prescribed by the laws of the State of Delaware and all
               rights conferred upon stockholders are granted subject to this
               reservation; PROVIDED, HOWEVER, that, notwithstanding any other
               provision of this Certificate of Incorporation or any provision
               of law which


                                       -4-

<PAGE>

               might otherwise permit a lesser vote or no vote, but in addition
               to any vote of the holders of any class or series of the stock of
               this Corporation required by law or by this Certificate of
               Incorporation, the affirmative vote of the holders of at least
               66-2/3% of the voting power of all of the then outstanding shares
               of the capital stock of the Corporation entitled to vote
               generally in the election of directors, voting together as a
               single class, shall be required to amend or repeal this Article
               NINTH, Article FIFTH, Article SIXTH, Article SEVENTH or Article
               EIGHTH.

     TENTH:    The name and mailing address of the incorporator is:

                                 Andrea Charvet

                                    ARTICLE I

                                  STOCKHOLDERS

     SECTION 1.1    ANNUAL MEETING.  An annual meeting of the stockholders, for
the election of directors to succeed those whose terms expire and for the
transaction of such other business as may properly come before the meeting,
shall be held at such place, on such date, and at such time as the Board of
Directors shall each year fix, which date shall be within thirteen months
subsequent to the later of the date of incorporation or the last annual meeting
of stockholders.

     SECTION 1.2    SPECIAL MEETING.  Special meetings of the stockholders, for
any purpose or purposes prescribed in the notice of the meeting, may be called
only (i) by the Board of Directors pursuant to a resolution adopted by a
majority of the total number of authorized directors (whether or not there
exists any vacancies in previously authorized directorships at the time any such
resolution is presented to the Board of Directors for adoption) or (ii) by the
holders of not less than 10% of all shares entitled to cast votes at the
meeting, voting together as a single class and shall be held at such place, on
such date, and at such time as they shall fix.  Business transacted at special
meetings shall be confined to the purpose or purposes stated in the notice.

     SECTION 1.3    NOTICE OF MEETING.  Written notice of the place, date, and
time of all meetings of the stockholders shall be given, not less than ten (10)
nor more than sixty (60) days before the date on which the meeting is to be
held, to each stockholder entitled to vote at such meeting, except as otherwise
provided herein or required by law (meaning, here and hereinafter, as required
from time to time by the Delaware General Corporation Law or the Certificate of
Incorporation of the Corporation).

     When a meeting is adjourned to another place, date or time, written notice
need not be given of the adjourned meeting if the place, date and time thereof
are announced at the meeting at which the adjournment is taken; provided,
however, that if the date of any adjourned meeting is more than thirty (30) days
after the date for which the meeting was originally noticed, or if a new record
date is fixed for the adjourned meeting, written notice of the place, date, and
time of the adjourned meeting shall be given in conformity herewith.  At any
adjourned meeting, any business may be transacted which might have been
transacted at the original meeting.

     SECTION 1.4    QUORUM.  At any meeting of the stockholders, the holders of
a majority of all of the shares of the stock entitled to vote at the meeting,
present in person or by proxy, shall constitute a quorum for all purposes,
unless or except to the extent that the presence of a larger number may be
required by law.

<PAGE>

     If a quorum shall fail to attend any meeting, the chairman of the meeting
or the holders of a majority of the shares of stock entitled to vote who are
present, in person or by proxy, may adjourn the meeting to another place, date,
or time.

     If a notice of any adjourned special meeting of stockholders is sent to all
stockholders entitled to vote thereat, stating that it will be held with those
present constituting a quorum, then except as otherwise required by law, those
present at such adjourned meeting shall constitute a quorum, and all matters
shall be determined by a majority of the votes cast at such meeting.

     SECTION 1.5    CONDUCT OF THE STOCKHOLDERS' MEETING.  At every meeting of
the stockholders, the Chairman, if there is such an officer, or if not, the
President of the Corporation, or in his absence the Vice President designated by
the President, or in the absence of such designation any Vice President, or in
the absence of the President or any Vice President, a chairman chosen by the
majority of the voting shares represented in person or by proxy, shall act as
Chairman.  The Secretary of the Corporation or a person designated by the
Chairman shall act as Secretary of the meeting.  Unless otherwise approved by
the Chairman, attendance at the stockholders' meeting is restricted to
stockholders of record, persons authorized in accordance with Section 8 of these
Bylaws to act by proxy, and officers of the Corporation.

     SECTION 1.6    CONDUCT OF BUSINESS.  The Chairman shall call the meeting to
order, establish the agenda, and conduct the business of the meeting in
accordance therewith or, at the Chairman's discretion, it may be conducted
otherwise in accordance with the wishes of the stockholders in attendance.  The
date and time of the opening and closing of the polls for each matter upon which
the stockholders will vote at the meeting shall be announced at the meeting.

     The Chairman shall also conduct the meeting in an orderly manner, rule on
the precedence of and procedure on, motions and other procedural matters, and
exercise discretion with respect to such procedural matters with fairness and
good faith toward all those entitled to take part.  The Chairman may impose
reasonable limits on the amount of time taken up at the meeting on discussion in
general or on remarks by any one stockholder.  Should any person in attendance
become unruly or obstruct the meeting proceedings, the Chairman shall have the
power to have such person removed from participation.  Notwithstanding anything
in the Bylaws to the contrary, no business shall be conducted at a meeting
except in accordance with the procedures set forth in this Section 1.6 and
Section 1.7, below.  The Chairman of a meeting shall, ff the facts warrant,
determine and declare to the meeting that business was not properly brought
before the meeting and in accordance with the provisions of this Section 1.6 and
Section 1.7, and if he should so determine, he shall so declare to the meeting
and any such business not properly brought before the meeting shall not be
transacted.

     SECTION 1.7    NOTICE OF STOCKHOLDER BUSINESS.  At an annual or special
meeting of the stockholders, only such business shall be conducted as shall have
been properly brought before the meeting.  To be properly brought before a
meeting, business must be (a) specified in the notice of meeting (or any
supplement thereto) given by or at the direction of the Board of Directors,
(b) properly brought before the meeting by or at the direction of the Board of
Directors, (c) properly brought before an annual meeting by a stockholder, or
(d) properly brought before a special meeting


                                       -2-

<PAGE>

by a stockholder, but if, and only if, the notice of a special meeting provides
for business to be brought before the meeting by stockholders.  For business to
be properly brought before a meeting by a stockholder, the stockholder must have
given timely notice thereof in writing to the Secretary of the Corporation.  To
be timely, a stockholder proposal to be presented at an annual meeting shall be
received at the Corporation's principal executive offices not less than 120
calendar days in advance of the date that the Corporation's (or the
Corporation's predecessor's) proxy statement was released to stockholders in
connection with the previous year's annual meeting of stockholders, except that
if no annual meeting was held in the previous year or the date of the annual
meeting has been changed by more than 30 calendar days from the date

of a special meeting, notice by the stockholder to be timely must be received
not later than the close of business on the tenth day following the day on which
such notice of the date of the meeting was mailed or such public disclosure was
made.  A stockholder's notice to the Secretary shall set forth as to each matter
the stockholder proposes to bring before the annual or special meeting (a) a
brief description of the business desired to be brought before the annual or
special meeting and the reasons for conducting such business at the special
meeting, (b) the name and address, as they appear on the Corporation's books, of
the stockholder proposing such business, (c) the class and number of shares of
the Corporation which are beneficially owned by the stockholder, and (d) any

every stockholder entitled to vote may vote in person or by proxy authorized by
an instrument in writing or by a transmission permitted by law filed in
accordance with the procedure established for the meeting.  No stockholder may
authorize more than one proxy for his shares.

     Each stockholder shall have one vote for every share of stock entitled to
vote which is registered in his or her name on the record date for the meeting,
except as otherwise provided herein or required by law.

     All voting, including on the election of directors but excepting where
otherwise required by law, may be by a voice vote; provided, however, that upon
demand therefor by a stockholder entitled to vote or his or her proxy, a stock
vote shall be taken.  Every stock vote shall be taken by ballots, each of which
shall state the name of the stockholder or proxy voting and such other
information as may be required under the procedure established for the meeting.
Every vote taken by ballots shall be counted by an inspector or inspectors
appointed by the chairman of the meeting.

     All elections shall be determined by a plurality of the votes cast, and
except as otherwise required by law, all other matters shall be determined by a
majority of the votes cast.

     SECTION 1.9    STOCK LIST.  A complete list of stockholders entitled to
vote at any meeting of stockholders, arranged in alphabetical order for each
class of stock and showing the address of each such stockholder and the number

such stockholder, for any purpose germane to the meeting, during ordinary
business hours for a period of at least ten (10) days prior to the meeting,
either at a place within the

notice of the meeting, or if not so specified, at the place where the meeting is
to be held.

     The stock list shall also be kept at the place of the meeting during the
whole time thereof and shall be open to the examination of any such stockholder
who is present.  This list shall presumptively determine the identity of the
stockholders entitled to vote at the meeting and the number of shares held by
each of them.

                               BOARD OF DIRECTORS

     SECTION 2.1    NUMBER AND TERM OF OFFICE.  The number of directors shall
initially be seven (7) and, thereafter, shall be fixed from time to time
exclusively by the Board of Directors pursuant to a resolution adopted by a
majority of the total number of authorized directors (whether or not there exist
any vacancies in previously authorized directorships at the time any such
resolution is presented to the Board for adoption).  Upon the closing of the
first sale of the Corporation's common stock pursuant to a firmly underwritten
registered public offering (the "IPO"), the directors shall be divided into
three classes, with the term of office of the first class to expire at the first
annual meeting of stockholders held after the IPO, the term of office of the
second class to expire at the second annual meeting of stockholders held after
the IPO; the term of office of the third class to expire at the third annual
meeting of stockholders held after the IPO; and thereafter for each such term to
expire at each third succeeding annual meeting of stockholders after such
election.  Such first class, second class and third class shall consist of
three, three and two directors, respectively.  A vacancy resulting from the
removal of a director by the stockholders as provided in Article II, Section 2.3
below may be filled at special meeting of the stockholders held for that
purpose.  All directors shall hold office until the expiration of the term for
which elected and until their respective successors are elected, except in the
case of the death, resignation or removal of any director.

     SECTION 2.2    VACANCIES AND NEWLY CREATED DIRECTORSHIPS.  Subject to the
rights of the holders of any series of Preferred Stock then outstanding, newly
created directorships resulting from any increase in the authorized number of
directors or any vacancies in the Board of Directors resulting from death,
resignation, retirement, disqualification or other cause (other than removal
from office by a vote of the stockholders) may be filled only  by a majority
vote of the directors then in office, though less than a quorum, and directors
so chosen shall hold office for a term expiring at the next annual meeting of
stockholders at which the term of office of the class to which they have been
elected expires.  No decrease in the number of directors constituting the Board
of Directors shall shorten the term of any incumbent director.

     SECTION 2.3    REMOVAL.  Subject to the rights of holders of any series of
Preferred Stock then outstanding, any directors, or the entire Board of
Directors, may be removed from office at any time, with or without cause, but
only by the affirmative vote of the holders of at least a majority of the voting
power of all of the then outstanding shares of capital stock of the Corporation
entitled to vote generally in the election of directors, voting together as a
single class.  Vacancies in the Board of


                                       -4-

<PAGE>

Directors resulting from such removal may be filled by a majority of the
directors then in office, though less than a quorum, or by the stockholders as
provided in Article II, Section 2.1 above.  Directors so chosen shall hold
office until the new annual meeting of stockholders.

     SECTION 2.4    REGULAR MEETINGS.  Regular meetings of the Board of
Directors shall be held at such place or places, on such date or dates, and at
such time or times as shall have been established by the Board of Directors and
publicized among all directors.  A notice of each regular meeting shall not be
required.

     SECTION 2.5    SPECIAL MEETINGS.  Special meetings of the Board of
Directors may be called by one-third of the directors then in office (rounded up
to the nearest whole number) or by the chief executive officer and shall be held
at such place, on such date, and at such time as they or he or she shall fix.
Notice of the place, date, and time of each such special meeting shall be given
each director by whom it is not waived by mailing written notice not fewer than
five (5) days before the meeting or by telegraphing or personally delivering the
same not fewer than twenty-four (24) hours before the meeting.  Unless otherwise
indicated in the notice thereof, any and all business may be transacted at a
special meeting.

     SECTION 2.6    QUORUM.  At any meeting of the Board of Directors, a
majority of the total number of authorized directors shall constitute a quorum
for all purposes.  If a quorum shall fail to attend any meeting, a majority of
those present may adjourn the meeting to another place, date, or time, without
further notice or waiver thereof.

     SECTION 2.7    PARTICIPATION IN MEETINGS BY CONFERENCE TELEPHONE.  Members
of the Board of Directors, or of any committee thereof, may participate in a
meeting of such Board or committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other and such participation shall constitute presence in
person at such meeting.

     SECTION 2.8    CONDUCT OF BUSINESS.  At any meeting of the Board of
Directors, business shall be transacted in such order and manner as the Board
may from time to time determine, and all matters shall be determined by the vote
of a majority of the directors present, except as otherwise provided herein or
requited by law.  Action may be taken by the Board of Directors without a
meeting if all members thereof consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the Board of Directors.

     SECTION 2.9    POWERS.  The Board of Directors may, except as otherwise
required by law, exercise all such powers and do all such acts and things as may

               (3)  To authorize the creation, making and issuance, in such form

negotiable, secured or unsecured, and to do all things necessary in connection
therewith;

cause, and from time to time to devolve the powers and duties of any officer
upon any other person for the time being;

               (5)  To confer upon any officer of the Corporation the power to
appoint, remove and suspend subordinate officers, employees and agents;

               (6)  To adopt from time to time such stock, option, stock
purchase, bonus or other compensation plans for directors, officers, employees
and agents of the Corporation and its subsidiaries as it may determine;

               (7)  To adopt from time to time such insurance, retirement, and

with these bylaws, for the management of the Corporation's business and affairs.

     SECTION 2.10   COMPENSATION OF DIRECTORS.  Directors, as such, may receive,
pursuant to resolution of the Board of Directors, fixed fees and other
compensation for their services as directors, including, without limitation,
their services as members of committees of the Board of Directors.

     SECTION 2.11   NOMINATION OF DIRECTOR CANDIDATES.  Subject to the rights of
holders of any class or series of Preferred Stock then outstanding, nominations
for the election of Directors may be made by the Board of Directors or a proxy
committee appointed by the Board of Directors or by any stockholder entitled to
vote in the election of Directors generally.  However, any stockholder entitled
to vote in the election of Directors generally may nominate one or more persons
for election as Directors at a meeting only if timely notice of such
stockholder's intent to make such nomination or nominations has been given in
writing to the Secretary of the Corporation.  To be timely, a stockholder
nomination for a director to be elected at an annual meeting shall be received
at the Corporation's principal executive offices not less than 120 calendar days
in advance of the date that the Corporation's (or the Corporation's
Predecessor's) Proxy statement was released to stockholders in connection with
the previous year's annual meeting of stockholders, except that if no annual
meeting was held in the previous year or the date of the annual meeting has been
changed by more than 30 calendar days from the date contemplated at the time of
the previous year's proxy statement, or in the event of a nomination for
director to be elected at a special meeting, notice by the stockholders to be
timely must be received not later than the close of business on the tenth day
following the day on which such notice of the date of the special meeting was
mailed or such public disclosure was made.  Each such notice shall set forth:
(a) the name and address of the stockholder who intends to make the nomination
and of the person or persons to be nominated; (b) a representation that the
stockholder is


                                       -6-

<PAGE>

a holder of record of stock of the Corporation entitled to vote for the election
of Directors on the date of such notice and intends to appear in person or by
proxy at the meeting to nominate the person or persons specified in the notice;
(c) a description of all arrangements or understandings between the stockholder
and each nominee and any other person or persons (naming such person or persons)
pursuant to which the nomination or nominations are to be made by the
stockholder; (d) such other information regarding each nominee proposed by such
stockholder as would be required to be included in a proxy statement filed
pursuant to the proxy rules of the Securities and Exchange Commission, had the
nominee been nominated, or intended to be nominated, by the Board of Directors;
and (e) the consent of each nominee to serve as a director of the Corporation if
so elected.

     In the event that a person is validly designated as a nominee in accordance
with this Section 2.11 and shall thereafter become unable or unwilling to stand
for election to the Board of Directors, the Board of Directors or the
stockholder who proposed such nominee, as the case may be, may designate a
substitute nominee upon delivery, not fewer than five days prior to the date of
the meeting for the election of such nominee, of a written notice to the
Secretary setting forth such information regarding such substitute nominee as
would have been required to be delivered to the Secretary pursuant to this
Section 2.11 had such substitute nominee been initially proposed as a nominee.
Such notice shall include a signed consent to serve as a director of the
Corporation, if elected, of each such substitute nominee.

     If the chairman of the meeting for the election of Directors determines
that nomination of any candidate for election as a Director at such meeting was
not made in accordance with the applicable provisions of this Section 2.11, such
nomination shall be void; provided, however, that nothing in this Section 2.11
shall be deemed to limit any voting rights upon the occurrence of dividend
arrearages provided to holders of Preferred Stock pursuant to the Preferred
Stock designation for any series of Preferred Stock.

     SECTION 8.1    RIGHT TO INDEMNIFICATION.  Each person who was or is made a
party or is threatened to be made a party to or is involved in any action, suit
or proceeding, whether civil criminal, administrative or investigative
("proceeding"), by reason of the fact that he or she or a person of whom he or
she is the legal representative, is or was a director, officer or employee of
the Corporation or is or was serving at the request of the Corporation as a
director, officer or employee of another corporation, or of a Partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, whether the basis of such proceeding is alleged action in an
official capacity as a director, officer or employee or in any other capacity
while serving as a director, officer or employee, shall be indemnified and held
harmless by the Corporation to the fullest extent authorized by Delaware Law, as
the same exists or may hereafter be amended (but, in the case of any such
amendment, only to the extent that such amendment permits the Corporation to
provide broader indemnification rights than said Law permitted the Corporation
to provide prior to such amendment) against an expenses, liability and loss
(including attorneys' fees, judgments, fines, ERISA excise taxes or penalties,
amounts paid or to be paid in settlement and amounts expended in seeking
indemnification granted to such person under applicable law, this bylaw or any
agreement with the Corporation) reasonably incurred or suffered by such person
in connection therewith and such indemnification shall continue as to a person
who has ceased to be a director, officer or employee and shall inure to the
benefit of his or her heirs, executors and administrators; PROVIDED, HOWEVER,
that,


                                      -11-

<PAGE>

except as provided in Section 8.2 of this Article VIII, the Corporation shall
indemnify any such person seeking indemnity in connection with an action, suit
or proceeding (or part thereof) initiated by such person only if (a) such
indemnification is expressly required to be made by law, (b) the action, suit or
proceeding (or part thereof) was authorized by the Board of Directors of the
Corporation, (c) such indemnification is provided by the Corporation, in its
sole discretion, pursuant to the powers vested in the Corporation under the
Delaware General Corporation Law, or (d) the action, suit or proceeding (or part
thereof) is brought to establish or enforce a right to indemnification under an
indemnity agreement or any other statute or law or otherwise as required under
Section 145 of the Delaware General Corporation Law.  Such right shall be a
contract right and shall include the right to be paid by the Corporation
expenses incurred in defending any such proceeding in advance of its final
disposition; PROVIDED, HOWEVER, that, unless the Delaware General Corporation
Law then so prohibits, the payment of such expenses incurred by a director or
officer of the Corporation in his or her capacity as a director or officer (and
not in any other capacity in which service was or is tendered by such person
while a director or officer, including, without limitation, service to an
employee benefit plan) in advance of the final disposition of such proceeding,
shall be made only upon delivery to the Corporation of an undertaking, by or on
behalf of such director or officer, to repay all amounts so advanced if it
should be determined ultimately that such director or officer is not entitled to
be indemnified under this Section or otherwise.

     SECTION 8.2    RIGHT OF CLAIMANT TO BRING SUIT.  If a claim under Section 1
of this Article VIII is not paid in full by the Corporation within ninety (90)
days after a written claim has been received by the Corporation, the claimant
may at any time thereafter bring suit against the Corporation to recover the
unpaid amount of the claim and, if such suit is not frivolous or brought in bad
faith, the claimant shall be entitled to be paid also the expense of prosecuting
such claim.  The burden of proving such claim shall be on the claimant.  It
shall be a defense to any such action (other then an action brought to enforce a
claim for expenses incurred in defending any proceeding in advance of its
disposition where the required undertaking, if any, has been tendered to this
Corporation) that the claimant has not met the standards of conduct which make
it permissible under the Delaware General Corporation Law for the Corporation to
indemnify the claimant for the amount claimed.  Neither the failure of the
Corporation (including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
Delaware General Corporation Law, nor an actual determination by the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) that the claimant has not met such applicable standard of conduct,
shall be a defense to the action or create a presumption that claimant has not
met the applicable standard of conduct.

     SECTION 8.3    NON-EXCLUSIVITY OF RIGHTS.  The rights conferred on any
person in Sections 1 and 2 shall not be exclusive of any other right which such
persons may have or hereafter acquire under any statute, provision of the
Certificate of Incorporation, bylaw, agreement, vote of stockholders or
disinterested directors or otherwise.

     SECTION 8.4    INDEMNIFICATION CONTRACTS.  The Board of Directors is
authorized to enter into a contract with any director, officer, employee or
agent of the Corporation, or any person serving at


                                      -12-

the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
including employee benefit plans, providing for indemnification rights
equivalent to or, if the Board of Directors so determines, greater than, those
provided for in this Article VIII.

     SECTION 8.5    INSURANCE.  The Corporation shall maintain insurance to the
extent reasonably available, at its expense, to protect itself and any such
director, officer, employee or agent of the Corporation or another corporation,
partnership, joint venture, trust or other enterprise against any such expense,
liability or loss, whether or not the Corporation would have the power to
indemnify such person against such expense, liability or loss under the Delaware
General Corporation Law.

     SECTION 8.6    EFFECT OF AMENDMENT.  Any amendment, repeal or modification
of any provision of this Article VIII by the stockholders and the directors of
the Corporation shall not adversely affect any right or protection of a director
or officer of the Corporation existing at the time of such amendment, repeal or
modification.

                                   AMENDMENTS

     SECTION 9.1    AMENDMENT OF BYLAWS.  The Board of Directors is expressly
empowered to adopt, amend or repeal Bylaws of the Corporation.  Any adoption,
amendment or repeal of Bylaws of the Corporation by the Board of Directors shall
require the approval of a majority of the total number of authorized directors
(whether or not there exist any vacancies in previously authorized directorships
at the time any resolution providing for adoption, amendment or repeal is
presented to the Board).  The stockholders shall also have power to adopt, amend
or repeal the Bylaws of the Corporation.  Any adoption, amendment or repeal of
Bylaws of the Corporation by the stockholders shall require, in addition to any
vote of the holders of any class or series of stock of the Corporation required
by law or by this Certificate of Incorporation, the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting
power of all of the then outstanding shares of the capital stock of the
Corporation entitled to vote generally in the election of directors, voting

               (a)  In the event Company shall receive from Holder a written
request that Company effect a registration on Form S-3 (and any related state
qualification or compliance) with respect to all or a part of the Registrable
Securities owned by Holder (a "Demand Registration"), Company shall:

                    (1)  as soon as reasonably practicable, and at its expense
as set forth in Section 3 hereof, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of Holder's
Registrable Securities as are specified in such request; provided, however, that
Company shall not be obligated to effect any such registration, qualification or
compliance, pursuant to this Section 2.1, (i) if Form S-3 (or any successor
form) is not available for such offering by Holder; (ii) if Holder proposes to
sell Registrable Securities in an aggregate amount less than 10% of the
Registrable Securities initially issued to Holder pursuant to the Reorganization
Agreement, as adjusted to reflect any event specified in Section 1.3(ii) hereof;
(iii) if two (2) Demand Registrations filed for Holder pursuant to this
Section 2.1 have become and remained effective and current as required by law
for the period required by Section 4.1 hereof; (iv) if Company has effected a
registration for Holder pursuant to this Section 2 within 365 days of the
receipt of such request; PROVIDED, HOWEVER, that so long as the number of shares
of Company Common Stock then held by Holder exceeds the greater of (x) 1% of the
Company's outstanding common stock and (y) the average weekly reported volume of
trading in such securities on all national securities exchanges and/or reported
through the Nasdaq Stock Market during Company's immediately preceding four full
calendar weeks, then such 365-day period shall be reduced to 180 days; (v) if
the request for a registration is made on or before the date that is 90 days
after the Effective Time of the Merger; (vi) in any particular jurisdiction in
which Company would be required to qualify to do business or to execute a
general consent to service of process in effecting such registration,
qualification or compliance; and (vii) at any time after three (3) years from
the date hereof;

                    (2)  subject to the foregoing, Company shall file a
registration statement on Form S-3 (or any successor form) covering the
Registrable Securities and use reasonable efforts to cause it to become and
remain effective, as soon as practicable after receipt of the request of Holder;
and

                    (3)  at the request of Holder or Manager, enter into and
perform its obligations under an underwriting or purchase agreement (the
"Underwriting Agreement") in customary form for secondary offerings of common
stock on Form S-3, and otherwise reasonably


                                        2

<PAGE>

acceptable to the parties, with the Manager (acting for itself and/or a group or
syndicate of underwriters) and Holder.

               (b)  It is agreed that with respect to any Demand Registration
requested pursuant to this Section 2.1, Company may defer the filing or
effectiveness of any registration statement related thereto for a reasonable
period of time not to exceed 90 days after such request if (A) Company is, at
such time, working on an underwritten public offering of Company Common Stock
("Company Common Stock Offering") and is advised by its managing underwriter(s)
that such offering would in its or their opinion be adversely affected by such
filing and Holder will be afforded an opportunity to include in such offering at
least 50% of its Registrable Securities as to which the request was made or
(B) Company determines, in its good faith and reasonable judgment, that any such
filing or the offering of any Registrable Securities would materially impede,
delay or interfere with any material proposed financing, offer or sale of
securities, acquisition, corporate reorganization or other significant
transaction involving Company; PROVIDED, HOWEVER, that with respect to
clause (B), Company gives Holder written notice of such determination; and
PROVIDED FURTHER, HOWEVER, with respect to both clauses (A) and (B), Company
shall not be entitled to postpone such filing or effectiveness if, within the
preceding 12 months, it had effected two postponements pursuant to this
Section 2.1(b) and, following such postponements, the Registrable Securities to
be sold pursuant to the postponed registration statements were not sold (for any
reason).

          2.2  PIGGYBACK REGISTRATION RIGHTS.  If at any time Company proposes
to register shares of Company Common Stock under the Securities Act solely for
the account of selling securityholders (other than a registration on Form S-8,
or any successor or similar forms), and is not precluded from including the
Registrable Securities of Holder in such registration by virtue of an existing
registration rights agreement, it shall each such time promptly give notice to
Holder of its intention to do so, of the SEC registration form that has been
selected by Company and of rights of Holder under this Section 2.2 (the
"Section 2.2 Notice").  Unless selling securityholders whose shares are included
on such registration statement have current rights to registration that would
preclude such proration, the Registrable Securities shall be included thereon
PRO RATA to those of the other selling securityholder or holders.
Notwithstanding the foregoing, (x) if, at any time after giving written notice
of its intention to register outstanding shares of Company Common Stock and
prior to the effective date of the registration statement filed in connection
with such registration, Company shall determine for any reason not to register
such outstanding equity securities, Company may, at its election, give written
notice of such determination to Holder and, thereupon, shall be relieved of its
obligation to register any Registrable Securities in connection with such
abandoned registration, without prejudice, however, to the rights of Holder
under Section 2.1 hereof, (y) in case of a determination by Company to delay
registration of Company Common Stock, Company shall be permitted to delay the
registration of such Registrable Securities for the same period as the delay in
registering such Company Common Stock, and (z) Company shall only be required to
include in the proposed registration that quantity of Registrable Securities as
will not, in the written opinion of the underwriters, jeopardize the success of
the offering by the Company.  No registration effected under this Section 2.2
shall relieve Company of its obligation to effect a Demand Registration under
Section 2.1 hereof.  Notwithstanding Section 4, Holder will be subject to the
procedures governing the other selling stockholders in any registration effected
under this Section 2.2.

     3.   EXPENSES OF REGISTRATION.  Whether or not any registration statement
prepared and filed pursuant to Section 2 hereof is declared effective by the SEC
(except where a Demand Registration is terminated, withdrawn or abandoned at the
written request of Holder), Company shall pay all expenses incident to Company's
performance of or compliance with the registration


                                        3

other persons, including special experts, retained by Company (collectively,
clauses (A) through (I), "Registration Expenses"); PROVIDED, HOWEVER, that
Company shall not be required to pay, and Holder shall pay, any discounts,
commissions or fees of underwriters, selling brokers and dealers relating to the
distribution of the Registrable Securities, and any fees and out-of-pocket
expenses of counsel selected by Holder in connection with the registration of
Registrable Securities.

Company pursuant to Section 2.1 of this Agreement, Company shall keep Holder

<PAGE>

request;

a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they are made, not misleading), and (F) of Company's determination that

<PAGE>

Company Common Stock to be issued for such number of shares of Company Common
Stock and registered in such names as Holder may reasonably request.

     5.   INDEMNIFICATION.

          5.1  Company shall indemnify and hold harmless Holder, each of its
directors, officers and agents, each underwriter (as defined in the Securities
Act) of Registrable Securities, if any, and each person who controls (within the
meaning of Section 15 of the Securities Act) Holder or any underwriter of the
Registrable Securities held by or issuable to Holder, against all claims,
losses, expenses, damages and liabilities, joint or several, including any of
the foregoing incurred in settlement of any proceeding, commenced or threatened,
(or actions in respect thereto) arising out of or based on any untrue statement
(or alleged untrue statement) of a material fact contained in any prospectus,
offering circular or other document (including any related registration
statement, notification or the like) incident to any such registration, or based
on any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
or any violation by Company of any rule or regulation promulgated under the
Securities Act or any state securities law applicable to Company and relating to
action or inaction required of Company in connection with any such registration,
and shall reimburse Holder, each of its directors, officers and agents, each
such underwriter and each person who controls Holder or any such underwriter for
any reasonable legal and any other expenses incurred in connection with
investigating, defending or settling any such claim, loss, damage, liability or
action, PROVIDED, HOWEVER, that Company shall not be liable in any such case to
the extent that any such claim, loss, damage or liability arises out of or is
based on any untrue statement or omission based upon written information
furnished to Company by Holder or such underwriter specifically for use therein.
The indemnity provided by this Section 5.1 shall be in addition to any liability
which Company may otherwise have.

          5.2  Holder shall indemnify and hold harmless Company, each of its
directors and officers, each underwriter, if any, and each person who controls
Company or any of the underwriters within the meaning of the Securities Act,
against all claims, losses, expenses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and shall reimburse
Company or underwriters for any reasonable legal or any other expenses incurred
in connection with investigating, defending or settling any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
pertaining to Holder, which is furnished in writing to Company by Holder
specifically for use therein.

          5.3  If the indemnification provided for in this Section 5 is
unavailable to or insufficient to hold harmless an Indemnified Party (as defined
below) in respect of any losses, claims, damages or liabilities (or actions in
respect thereof) referred to therein, then Company and Holder shall contribute
to the amount paid or payable as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of Company on the one hand and Holder on the other
in connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations.  Relative fault shall be determined by
reference to, among


                                        7

<PAGE>

other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by Company on the one hand or Holder on the other and such
person's relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  Company agrees that it would not
be just and equitable if contribution pursuant to this Section 5.3 were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to above in this
Section 5.3.  The amount paid or payable by a party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this Section 5.3 shall include any legal or other expenses reasonably
incurred by such party in connection with investigating or, except as provided
in Section 5.4 hereof, defending any such action or claim.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  No person shall be required to
contribute to any settlement effected without its consent, which consent shall
not be unreasonably withheld.  If, however, indemnification is available under
this Section 5, the indemnifying parties shall indemnify each indemnified party
to the fullest extent provided in Sections 5.1 to 5.3 hereof without regard  to
the relative fault of such indemnifying party or indemnified party or any other
equitable considerations.

          5.4  Each party entitled to indemnification under this Section 5 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld), and the Indemnified Party may participate in such defense at such
party's expense, unless the Indemnified Party in its reasonable judgment
determines that joint representation by counsel for the Indemnifying Party would
be inappropriate due to actual or potential differing interests between the
Indemnifying Party and the Indemnified Party in the conduct of the defense of
such action, in which case the Indemnified Party shall be entitled to be
represented by separate counsel selected by it, the reasonable fees and expenses
of which shall be borne by the Indemnifying Party, and provided further that the
failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations hereunder, unless such failure
resulted in actual detriment to the Indemnifying Party.  No Indemnifying Party,
in the defense of any such claim or litigation, shall, except with the consent
of each Indemnified Party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect of such claim or litigation.

          5.5  Notwithstanding the foregoing, to the extent that the provisions
on indemnification of the underwriters and their controlling persons contained
in the Underwriting Agreement in connection with an underwritten public offering
are in conflict with the foregoing provisions, the provisions in the
Underwriting Agreement shall control as to indemnification of the underwriters
and their controlling persons in the public offering.

          5.6  Notwithstanding the foregoing, in no event shall Holder be liable
under this Section 5 for an amount exceeding the net proceeds received by Holder
from the sale of its Registrable Securities pursuant to the registration rights
granted to Holder hereunder.

     6.   INFORMATION BY HOLDER.  Holder shall promptly furnish to Company such
information


                                        8

<PAGE>

regarding Holder as Company may reasonably request and as shall be required in
connection with any registration referred to herein.

     7.   ELIGIBILITY FOR FORM S-3.  Company agrees that, until its obligations
to effect registrations pursuant to this Agreement have been discharged and
Holder is able to make sales of Registrable Securities pursuant to Rule 145(d)
under the Securities Act without compliance with any of the provisions of
Rule 144 thereunder, Company shall remain eligible to register the Registrable
Securities on Form S-3.

     8.   RULE 144.  Company agrees that, until its obligations to effect
registrations pursuant to this Agreement have been discharged and Holder is able
to make sales of Registrable Securities pursuant to Rule 145(d) under the
Securities Act without compliance with any of the provisions of Rule 144
thereunder, Company shall (A) comply with the requirements of Rule 144(c), as
such rule may be amended from time to time (or any similar rule or regulation
hereafter adopted by the SEC), regarding the availability of current public
information to the extent required to enable Holder to sell Registrable
Securities without registration under the Securities Act pursuant to Rule 144
(or any similar rule or regulation), and (B) furnish to Holder upon request a
written statement by Company that it has complied with the requirements of Rule
144(c) and of the Securities Act of the Securities Exchange Act of 1934, as
amended.

     9.   EXECUTION; AMENDMENTS.  This Agreement may be executed in
counterparts, all of which shall constitute a single instrument.  This Agreement
may be amended only by a writing signed by Holder and Company.

     10.  NOTICES, ETC.  All notices and other communications required or
permitted hereunder shall be in writing and shall be sent by recognized overseas
air courier, telecopied (and confirmed by written letter mailed or delivered as
soon as practicable thereafter) or otherwise delivered by hand or by messenger,
addressed (i) if to Holder, at its address stated in or furnished pursuant to
the Reorganization Agreement or at such other address as Holder shall have
furnished to Company or (ii) if to Company, at its address stated in or
furnished pursuant to the Reorganization Agreement or at such other address as
Company shall have furnished to Holder.  Each such notice or other communication
shall for all purposes of this Agreement be treated as effective or having been
given when delivered if delivered personally, when received if telecopied or, if
sent by a recognized overseas air courier, at the earlier of its receipt or
72 hours after the same has been deposited with such air courier.

     11.  This Agreement represents the entire agreement and understanding
between the parties hereto with respect to the subject matter hereof and
supersedes any and all prior oral and written agreements, arrangements and
understandings between the parties hereto with respect to such subject matter;
and any provision hereof can be waived only by a written instrument making
specific reference to this Agreement signed by Company on the one hand, and
Holder on the other hand.

     12.  This Agreement shall be binding upon and shall inure to benefit of the
parties hereto and their respective successors.

     13.  The paragraph and section headings contained in this Agreement are for
general reference purposes only and shall not affect in any manner the meaning,
interpretation or construction of the terms or other provisions of this
Agreement.


                                        9

<PAGE>

     14.  This Agreement shall be governed by, construed and enforced in
accordance with the laws of the State of California applicable to contracts to
be made, executed, delivered and performed wholly within such state and, in any
case, without regard to the conflicts of law principles of such state.

     15.  If at any time subsequent to the date hereof, any provision of this
Agreement shall be held by any court of competent jurisdiction to be illegal,
void or unenforceable, such provision shall be of no force and effect, but the
illegality or unenforceability of such provision shall have no effect upon and
shall not impair the enforceability of any other provision of this Agreement.

     16.  Company acknowledges that it would be impossible to determine the
amount of damages that would result form any breach by it of any of the
provisions of this Agreement and the remedy at law for any breach, or threatened
breach, of any such provisions would likely be inadequate and, accordingly,
agrees that Holder shall, in addition to any other rights or remedies which it
may have, be entitled to seek such equitable and injunctive relief as may be
available from any court of competent jurisdiction to compel specific
performance of, or restrain Company from violating any of, such provisions.  In
connection with any action or proceeding for injunctive relief, Company hereby
waives the claim or defense that a remedy at law alone is adequate and agrees,
to the maximum extent permitted by law, to have such provision of this Agreement
specifically enforced against it, without the necessity of posting bond or other
security against it, and consents to the entry of injunctive relief against it
enjoining or restraining any breach or threatened breach of this Agreement.

     17.  Any controversy, dispute or claim arising out of or relating to this
Agreement or the breach hereof which cannot be settled by mutual agreement shall
finally be settled by a court of competent jurisdiction in Santa Clara County,
California.

     18.  The failure of any party at any time or times to require performance
of any provision hereof shall not affect the right at a later time to enforce
the same.  No waiver by any party of any condition, and no breach of any
provision, term, covenant, representation or warranty contained in this
Agreement, whether by conduct or otherwise, in any one or more instances, shall
be deemed to be construed as a further or continuing waiver of any such
condition or of the breach of any other provision, term, covenant,
representation or warranty of this Agreement.

          (a)  On and after the Effective Date, as among the Parties, DiviCom

<PAGE>

          (d)  a non-exclusive, royalty-free, perpetual, worldwide license to
use all documentation relating to the Licensed ASICs, Licensed Consumer
Decoders, Licensed MPEG Software Tools, and Licensed System Product Documents,
as described in EXHIBIT A (collectively, the "LICENSED DIVICOM PRODUCT
DOCUMENTATION") solely for the purposes of exercising the licenses granted above
and in Section 4.2(a) below.

     The foregoing licenses and rights may not be sublicensed or otherwise
transferred, in whole or in part, by SAGEM to any third party other than a SAGEM
Affiliate provided that such Affiliate agrees to be bound by the terms hereof
and provided further that such sublicense or other transfer shall terminate if
and at such time that such Affiliate ceases to be an Affiliate.  Notwithstanding
the foregoing, SAGEM shall be permitted to subcontract development and
manufacturing services and in connection therewith, SAGEM shall be permitted to
provide its subcontractors with all licensed DiviCom Technology including,
without limitation, Licensed MPEG Software Tools (in object code only) and
Licensed DiviCom Product Documentation in accordance with the confidentiality
and use restrictions described herein.  Except as otherwise specifically
provided for in this Agreement, DiviCom will be under no obligation to provide
any modifications, improvements, derivative works or enhancements of DiviCom
Products or DiviCom Technology to SAGEM or any other Party.  Further, to the
extent that any license herein granted to SAGEM is a license of software, said
software shall be provided in source code (to the extent such exists) with the
exception of TRIX Technology which shall be provided as detailed in Section 2(c)
of EXHIBIT A hereto.

     4.2  SYSTEMS LICENSES AND DISTRIBUTORSHIP RIGHTS.  As of the Effective
Date, DiviCom hereby grants to SAGEM the following licenses and rights:

          (a)  a royalty-free license to sell, lease, provide customer support
services and distribute in Europe and sublicense object code versions of any
software contained therein solely to end users (without any right by such
sublicensee to copy or further sublicense) DiviCom Systems purchased directly
from DiviCom until the second anniversary of the Effective Date.  The foregoing
license shall be non-exclusive; provided, however, that 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;
and

          (b)  DiviCom agrees to furnish SAGEM, on a Most Favored Customer Basis
with respect to price terms, such quantities of DiviCom Systems as are
commercially practicable for DiviCom to furnish and as SAGEM may reasonably
request from time to time.

          Except as otherwise provided above, the foregoing licenses and rights
may not be sublicensed or otherwise transferred, in whole or in part, by SAGEM
to any third party other than a SAGEM Affiliate provided that such Affiliate
agrees to be bound by the terms hereof and provided further that such sublicense
or other transfer shall terminate if and at such time that such Affiliate ceases
to be an Affiliate.

     4.3  PROCUREMENT OF ASIC CHIPS.  DiviCom and SAGEM acknowledge that DiviCom
and SAGEM currently procure the ASIC Chips from certain foundries (the "CURRENT
ASIC


                                       -5-

<PAGE>

PROVIDERS").  DiviCom agrees that it will continue to authorize the Current ASIC
Providers to furnish ASIC Chips to SAGEM for so long as the Current ASIC
Providers continue to furnish such products to DiviCom.  In the event that,
after the Effective Date, DiviCom ceases to obtain ASIC Chips from the Current
ASIC Providers because C-Cube has commenced manufacture of ASIC Chips
internally, C-Cube agrees to furnish ASIC Chips to SAGEM on a Most Favored
Customer Basis with respect to price, warranty and current release terms, or, if
C-Cube is not furnishing ASIC Chips to any third party, C-Cube and SAGEM agree
to negotiate in good faith to determine a reasonable basis by which C-Cube will
furnish such ASIC Chips to SAGEM.  The Parties acknowledge that none of the
Current ASIC Providers nor C-Cube is obligated to ensure any particular
quantities to SAGEM nor to continue to manufacture the ASIC Chips, it being
further acknowledged that Section 4.1(a) gives SAGEM rights to manufacture or
have manufactured the same.  The Parties further agree that it is in their
mutual best interests to cooperate with each other so that each Party may obtain
the full benefit of the bargain of this Agreement.  In furtherance thereof, but
without creating or imposing any obligation whatsoever, SAGEM intends to
purchase ASIC's from C-Cube to the extent C-Cube is able to satisfy and fulfill
SAGEM's requirements including, without limitation, those pertaining to quantity
and price.

     4.4  THIRD-PARTY RIGHTS.  The Parties acknowledge that certain DiviCom
Products and DiviCom Technologies contain certain Intellectual Property Rights
of third parties that have been licensed to DiviCom as have been or will be
provided in writing prior to the Effective Date ("THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS").  DiviCom hereby grants to SAGEM only those rights, if any, as
sublicensee, to the Third Party Intellectual Property Rights as (i) it is
currently permitted (and without any representation as to the scope of such
rights or the Third-Party Intellectual Property Rights to which they relate) to
convey to SAGEM and (ii) which shall not require any additional payment by
DiviCom to such third parties, which rights shall, as limited by the foregoing,
be considered to be incorporated in the licenses granted herein.  SAGEM
acknowledges and agrees that subject to the foregoing, it must obtain licenses
directly from such third parties before it may exercise any Third-Party
Intellectual Property Rights with respect to such licenses and that it may be
required to pay royalties to third parties to obtain such licenses.  DiviCom
makes no representation that such licenses may be available to SAGEM on terms
acceptable to SAGEM, if at all.

     4.5  LICENSED DIVICOM PRODUCT DOCUMENTATION.  Within thirty (30) days after
the date of this Agreement, DiviCom will have delivered to SAGEM the Licensed
DiviCom Product Documentation (including both decoder and system documentation
as well as documentation in DiviCom's possession in existence as of the date of
this Agreement pertaining to Third Party Intellectual Property Rights to the
extent such documentation exists and may be provided without consent of or
payment by DiviCom to any party, and without any loss of any rights DiviCom may
be entitled to pursuant to such documentation) described in EXHIBIT A hereto.
DiviCom hereby represents and warrants that the documentation DiviCom will
provide to SAGEM pursuant to the foregoing sentence will constitute the latest
full versions of all written materials prepared by DiviCom employees and
consultants and made available for internal use by DiviCom (and shall constitute
the latest revisions and versions of such documentation as it pertains to the
licensed DiviCom Products or DiviCom Technology as identified in EXHIBIT A but
excluding personal notes, log books, crib notes and the like) as of the date of
this Agreement (or such earlier date(s) as indicated in EXHIBIT A) in


                                       -6-

<PAGE>

connection with the technology described in EXHIBIT A.  During the thirty (30)
days following delivery of the last document to be delivered pursuant to the
foregoing sentence, SAGEM will review the materials delivered and at the end of
such time will provide DiviCom with a list of any issues regarding the
documentation itself, including any questions as to whether it includes all
documentation required to be delivered.  The Licensed DiviCom Product
Documentation may only be used by SAGEM in accordance with this Agreement,
including with the terms of Section 9 hereof (Confidential Information).

5.   MAINTENANCE AND SUPPORT

     5.1  SUPPORT SERVICES.  Subject to DiviCom entering into an arrangement
with another distributor with respect to DiviCom Products that are licensed to
SAGEM hereunder in which case DiviCom will provide support services to SAGEM
customers on a Most Favored Customer Basis, DiviCom will provide the standard
support services described in EXHIBIT B hereto for all DiviCom Products sold or
committed to be sold by SAGEM.  The Parties acknowledge that DiviCom may from
time to time modify and change the standard terms and conditions in EXHIBIT B,
and the Parties agree that upon any such change, DiviCom shall be bound to
provide support services only with respect to the then current terms and
conditions.  The Parties further agree that in the event of any conflict between
the terms and conditions in EXHIBIT B and the other provisions of this
Agreement, including all other exhibits hereto, the other provisions of this
Agreement, including all other exhibits hereto, shall control.  Upon terms and
conditions to be mutually agreed upon between DiviCom and SAGEM, such support
services may be extended.

     5.2  DIVICOM SYSTEMS SOFTWARE.  DiviCom agrees to furnish to SAGEM, in the
form of a master disc (in object code only), the next version of DiviCom Systems
software to be released by DiviCom after the date of this Agreement (the
Springdale software), as soon as such software is available, at no additional
cost to SAGEM, and for use by SAGEM solely for purposes of licensing such
software to SAGEM's customers who have been shipped DiviCom Systems by SAGEM.
DiviCom further agrees that the standard terms and conditions in EXHIBIT B for
DiviCom Systems that are provided by DiviCom to such SAGEM customers will
extend, with respect to each such SAGEM customer, to the later of (i) the date
that is ninety (90) days after DiviCom furnishes to SAGEM the DiviCom System
software described in the foregoing sentence or (ii) the first anniversary of
the date such SAGEM customer was shipped a DiviCom System by SAGEM.

     5.3  SALES SUPPORT ENGINEERING.  While DiviCom will have no obligation to
train SAGEM personnel to utilize the Licensed DiviCom Product Documentation or
the DiviCom Technology, DiviCom will provide, solely with regard to the Licensed
DiviCom Product Documentation, for a period ending on the first anniversary of
the Effective Date, up to two man days per month of sales support engineering.

a significant supply agreement (the "Supply Agreement") with a communications
company for DiviCom Systems and decoders in which SAGEM will serve as a
manufacturer and supplier of DiviCom Products.  A Memorandum of Understanding

a third party to manufacture and supply such communications company with the
DiviCom Products to be supplied by SAGEM, SAGEM will be entitled to terms on a
Most Favored Customer Basis, provided that in no event shall the royalty payable

7.   REPRESENTATIONS AND WARRANTIES

     7.1  MUTUAL REPRESENTATIONS AND WARRANTIES.  Each Party represents and
warrants, severally and not jointly, to each of the other Parties that:

          (a)  such Party has full power, right and authority to enter into this
Agreement, to carry out its obligations under this Agreement, including the
superseding of the Prior Agreements, and to the extent applicable, to grant,
assign and license the rights that are granted, assigned and licensed to any
other Party under this Agreement;

          (b)  neither the execution and delivery of this Agreement, nor the
performance of any of such Party's obligations hereunder, will conflict with, or
result in a termination, breach, impairment or violation of any material
agreement between such Party and any third party (other than the termination of
each of the Prior Agreements);

          (c)  the performance of such Party's obligations hereunder will not
require the consent of any third party not a Party hereto;

          (d)  this Agreement, when duly executed by each Party, will constitute
a valid and binding obligation of such Party, enforceable in accordance with its
terms; and

          (e)  such Party has not previously granted or assigned and will not
grant or assign any Intellectual Property Rights to any third party which are
inconsistent with the rights that are granted and assigned herein.

     7.2  AGREEMENT TO COOPERATE TO RESOLVE ANY INFRINGEMENT OF THIRD PARTY
INTELLECTUAL PROPERTY RIGHTS.  Each of DiviCom and SAGEM agrees to promptly
notify the other of any infringement or unauthorized use or variation of the
DiviCom Technology licensed hereunder by others promptly following such Party's
becoming aware of facts relating to such event, and then of such Party's
conclusion, if any, that such infringement or use exists.  DiviCom shall have
the initial right to determine whether or not to bring infringement or unfair
competition or related proceedings on account of any such infringement or
unauthorized use or variation, or any other matter involving the DiviCom
Technology generally, and may institute, defend or settle claims, actions or
proceedings at its sole cost and expense.  If within thirty (30) days after
receipt of notice of such conclusion with respect to any such claim (or such
shorter period as reasonable under the circumstances), DiviCom refuses to
prosecute such action or fails to give written notice to SAGEM that it will
prosecute such action, then SAGEM shall have the right, after first giving
DiviCom written notice, to institute, defend or settle such action or claim or
proceeding at its sole cost and expense.  DiviCom and SAGEM, as the case may be,
shall each cooperate fully with the other in any legal action taken by the


                                      -10-

<PAGE>

other against any party alleged to be infringing upon the DiviCom Technology.
If SAGEM is prosecuting or defending the action, then SAGEM shall be entitled to
name DiviCom as a party to such action if necessary in SAGEM's reasonable
judgment.  Any amount awarded with respect to any legal action brought hereunder
shall first be used to reimburse all costs expended and the remainder shall be
allocated equitably between SAGEM and DiviCom unless otherwise agreed to by
SAGEM and DiviCom.  Any disputes as to which Party has the right to prosecute
the action, or as to allocation of proceeds from the action, shall be settled by
arbitration as provided in Section 11.3.

     7.3  NO OTHER WARRANTIES.  THE WARRANTIES SET FORTH IN THIS SECTION 7 ARE
THE SOLE AND EXCLUSIVE WARRANTIES MADE BY EACH PARTY HEREUNDER AND ARE IN LIEU
OF ALL OTHER WARRANTIES, WHETHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED
TO, ANY IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE, NON-INFRINGEMENT OR WARRANTY OF TITLE, ALL OF WHICH ARE HEREBY
EXPRESSLY DISCLAIMED.

PARTY") will:  (i) promptly notify the Party from whom indemnification is sought
(the "INDEMNIFYING PARTY") of the claim; (ii) provide the Indemnifying Party
with all reasonable information and assistance; and (iii) grant the Indemnifying
Party authority and control of the defense or settlement of such claim.  The
Indemnifying Party shall not settle any such claim without the Indemnified
Party's prior written consent, which consent will not be unreasonably withheld.
The Indemnified Party reserves the right to retain counsel, at its expense, to
participate in the defense and settlement of any such claim.

     8.3  LIMITATIONS OF LIABILITY.  REGARDLESS OF WHETHER ANY REMEDY SET FORTH
HEREIN FAILS OF ITS ESSENTIAL PURPOSE, IN NO EVENT WILL ANY PARTY BE LIABLE TO
ANY OTHER PARTY FOR ANY FORM OF SPECIAL, INCIDENTAL, INDIRECT, CONSEQUENTIAL, OR
PUNITIVE DAMAGES, WHETHER OR NOT FORESEEABLE (INCLUDING, WITHOUT LIMITATION
DAMAGES FOR LOSS OF BUSINESS PROFITS, BUSINESS INTERRUPTION, LOSS OF BUSINESS

          and not readily ascertainable by proper means by, third
          parties.

     9.2  EXCLUSIONS.  No Party will be liable for the disclosure of
Confidential Information if such information:

Confidential Information.  Without limitation of the foregoing, each Party
agrees not to disclose Confidential Information to any other person, firm or
