                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's Board of Directors to grant, indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act. Article
VI of the Company's Bylaws provides for the mandatory indemnification of its
directors, officers, employees and other agents to the maximum extent permitted
by Delaware General Corporation Law, and the Company has entered into agreements
with its officers, directors and certain key employees implementing such
indemnification.

ITEM 22.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at the time shall be deemed to be
the initial bona fide offering thereof.

     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 is 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.

     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
issuer 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.

     The registrant undertakes that every prospectus: (i) that is filed pursuant
to the immediately preceding paragraph, 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.

     Insofar as 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.

     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

                                      II-2
<PAGE>   4

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.

     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.

Harmonic, Inc.

     RE: REGISTRATION STATEMENT ON FORM S-4 (REG. NO. 333-__________________)

Gentlemen:

     We have acted as counsel for Harmonic, Inc., a Delaware corporation (the
"Company"), in connection with the merger (the "Merger") of C-Cube
Microsystems, Inc. ("C-Cube Microsystems") into the Company after the proposed
spin-off by C-Cube Microsystems of its semiconductor business, and the issuance
and registration of shares of the Company's Common Stock, par value $.001 per
share (the "Shares"), in connection with the Merger. The Company proposes to
issue the Shares in exchange for shares of C-Cube Microsystems' Common Stock,
par value $0.001 per share, as described in the above-referenced Registration
Statement on Form S-4 (the "Registration Statement") under the Securities Act
of 1933, as amended (the "Act"). In connection therewith, we have examined,
among other things, the Registration Statement, as well as the proceedings and
other actions taken by the Company in connection with the authorization of the
Shares and such other matters as we deemed necessary for purposes of rendering
this opinion.

     Based on the foregoing, and in reliance thereon, we are of the opinion
that (i) the Shares have been duly authorized and (ii) upon issuance of the
Shares in connection with the Merger as described in the Registration Statement
and the Prospectus constituting a part thereof (the "Prospectus"), the Shares
will be validly issued, fully paid and non-assessable.

    The Company is a Delaware corporation. This opinion is limited to the
present laws of the State of Delaware and to the present federal laws of the
United States of America.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to this firm under the heading
"Legal Matters" contained in this Prospectus. In giving this consent, we do not
admit that we are within the category of persons whose consent is required
under Section 7 of the Act or the General Rules and Regulations of the
Securities and Exchange Commission.

                                        Very truly yours,

Harmonic Inc.
549 Baltic Way
Sunnyvale, California 94089

     Re:  Registration Statement on Form S-4

Ladies and Gentlemen:

     We have acted as counsel to Harmonic Inc., a Delaware corporation
("Harmonic"), in connection with the preparation and execution of the Amended
and Restated Agreement and Plan of Merger and Reorganization (the "Merger
Agreement"), dated as of December 9, 1999, by and between Harmonic and C-Cube
Microsystems Inc., a Delaware corporation ("C-Cube"). Pursuant to the Merger
Agreement, C-Cube will merge with and into Harmonic, with Harmonic surviving the
merger (the "Merger"). The Merger and certain proposed transactions incident
thereto are described in the Registration Statement on Form S-4 (the
"Registration Statement") of Harmonic, which includes the Joint Proxy
Statement/Prospectus/Information Statement of C-Cube and Harmonic ("Joint Proxy
Statement"), and which is to be filed with the U.S. Securities and Exchange
Commission under the Securities Act of 1933 on the date hereof.

     You have requested our opinion regarding certain federal income tax
consequences of the Merger. In connection with rendering this opinion, we have
assumed and relied upon (without any independent investigation):

     1.   The truth and accuracy of the statements, covenants, representations
and warranties contained in the Merger Agreement, in the representations
received from Harmonic and C-Cube (the "Tax Representation Letters") that have
been provided to us and that were issued in support of this opinion, and in the
Registration Statement;

<PAGE>   2

     2.   consummation of the Merger in accordance with the Merger Agreement,
without any waiver, breach or amendment of any material provisions of the Merger
Agreement, the effectiveness of the Merger under applicable state law, and the
performance of all covenants contained in the Merger Agreement and the Tax
Representation Letters without waiver or breach of any material provisions
thereof;

     3.   the accuracy of any representation or statement made "to the knowledge
of" or similarly qualified without such qualification, and as to all matters in
which a person or entity is making a representation, that such person or entity
is not a party to, does not have, or is not aware of, any plan, intention,
understanding or agreement inconsistent with such representation, and there is
no such plan, intention, understanding, or agreement inconsistent with such
representation;

     4.   the reporting of the Merger as a reorganization, within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"), by
Harmonic in its federal income return; and

     5.   the authenticity of original documents (including signatures),
conformity to the originals of documents submitted to us as copies, and due
execution and delivery of all documents where due execution and delivery are
prerequisites to effectiveness thereof.

     Based upon the foregoing, the discussion contained in the Joint Proxy
Statement under the caption "Material Federal Income Tax Consequences of the
Merger," subject to the limitations and qualifications described therein and
herein, is our opinion with respect to the material United States federal income
tax consequences generally applicable to the Merger.

     This opinion represents our best judgment regarding the application of
federal income tax laws under the Code, existing judicial decisions,
administrative regulations and published rulings and procedures. Because this
opinion is being delivered prior to the Effective Time of the Merger, it must be
considered prospective and dependent on future events. Our opinion is not
binding upon the Internal Revenue Service or the courts, and there is no
assurance that the Internal Revenue Service will not successfully assert a
contrary position. Furthermore, no assurance can be given that future
legislative, judicial or administrative changes, on either a prospective or
retroactive basis, would not adversely affect the accuracy of the conclusions
stated herein. We undertake no responsibility to advise you of any new
developments in the application or interpretation of the federal income tax
laws. Furthermore, in the event any one of the statements, covenants,
representations, warranties or assumptions upon which we have relied to issue
this opinion is incorrect, our opinion might be adversely affected and may not
be relied upon.

     This opinion addresses only the matters described above, and does not
address any other federal, state, local or foreign tax consequences that may
result from the Merger or any other transaction undertaken in connection with
the Merger.

     This opinion is rendered only to Harmonic and its stockholders and is
solely for their benefit in connection with filing the Registration Statement
with the Securities and Exchange Commission. This opinion may not be relied upon
for any other purpose or by any other person or entity, and may not be

                                       2

furnished to, quoted to or by or relied upon by any other person or entity,
without our prior written consent. We hereby consent to the use of this opinion
as an exhibit to the Registration Statement and to the use of our name under the
caption "Material Federal Income Tax Consequences" in the Joint Proxy Statement.
In giving such consent, we do not thereby admit that we are in the category of
persons whose consent is required under Section 7 of the Securities Act of 1933,
as amended, nor do we thereby admit that we are experts with respect to any part
of such Registration Statement within the meaning of the term "experts" as used
in the Securities Act of 1933, as amended.

                                       Very truly yours,

         appropriate per unit price adjustment. Taxes are not included in prices
         and will be invoiced, if applicable, as a separate item.

5.3      [***]: HHH shall pay the prices specified in Exhibit A for the
         Component Products; provided that in no event shall [***].

5.4      PAYMENT:

         (a)      HHH warrants to CCC that it is financially solvent on the date
                  on which it places an order and expects to be solvent on the
                  date of receipt of shipment.

         (b)      HHH shall pay all invoices per the terms stated on the
                  invoice. CCC reserves the right to terminate or modify terms
                  of credit payments when, in CCC's sole discretion, CCC
                  believes that payment may be at risk.

         (c)      Interest shall accrue daily on sums not paid within [***]
                  after the date of invoice at the lesser of a monthly rate of

         (a)      Delivery shall be Ex-works CCC's point of shipment. Title and
                  risk of loss shall pass to HHH and Component Products shall be
                  deemed accepted upon delivery to a common carrier at CCC's
                  point of shipment, the carrier acting as HHH's agent. HHH
                  shall pay all transportation and insurance charges. The HHH
                  may specify a carrier acceptable to CCC (acceptance will not
                  unreasonably be withheld). In the absence of specific
                  instructions by HHH, the carrier will be selected by CCC.

         (b)      Any delivery dates provided by CCC to the HHH are best
                  estimates only. CCC reserves the right to make deliveries in
                  installments which shall not relieve HHH of its obligation to
                  accept and pay for remaining deliveries.

         (c)      CCC reserves the right to make shipments at any time up to
                  [***] days prior to the requested delivery date and HHH shall
                  not reject tendered Component Products for the sole reason of
                  such early delivery. Claims for shipment shortage shall be
                  deemed waived unless presented to CCC in writing or by
                  electronic transmission within [***] of delivery.

5.6      SOFTWARE LICENSE AND SOFTWARE OWNERSHIP: Subject to Sections 2.1, 2.5,
         3.1, 4.3, and 4.7 of this Agreement, CCC shall retain all right, title
         and ownership of any CCC Licensed Software provided to HHH or its end
         users.

5.7      NO OTHER LICENSE: The Component Products are offered for sale and are
         sold by CCC subject to the condition that such sale does not convey any
         license, expressly or by implication, to manufacture, reverse engineer,
         duplicate or otherwise copy or reproduce any of the Component Products
         or CCC Licensed Software without CCC's express written permission.

5.8      RESTRICTED USE: CCC's Component Products may produce a reduction or
         loss of data and therefore are not sold for use in medical equipment,
         avionics, nuclear application, or any other high risk applications
         where malfunctions or loss of data could directly or indirectly result
         in personal injury. HHH agrees not to allow the use of CCC's Component
         Products in such applications and HHH agrees to indemnify CCC and to
         hold CCC harmless against any liability to CCC arising out of HHH's
         breach of such agreement.

5.9      CANCELLATION AND RESCHEDULES:

         (a)      No cancellation or reschedule of any portion of an order is
                  permitted within [***] of the scheduled shipment of that
                  portion of the order.

         (b)      In the event that HHH cancels any order more than [***] but
                  fewer than [***] prior to the scheduled delivery date for
                  such order, HHH shall pay to CCC a restocking/cancellation fee
                  equal to [***] of the purchase price for the Component
                  Products subject to such order.

         (c)      Component Products that have been developed for or shippable
                  to a single customer shall be considered custom products.
                  "Single customer" shall include the customer and all its
                  subsidiary or parent corporations, and any divisions of

                  such entities. Custom Component Products may not be canceled
                  or rescheduled within [***] of the scheduled shipment date.

         (d)      CCC shall not be liable for any delay or failure to perform
                  due to any cause beyond its control. In the case of a delay
                  for any reason whatsoever, the delivery schedule shall be
                  considered extended by a period of time equal to the time
                  lost. In the event CCC is unable to wholly or partially
                  perform because of any cause beyond its control, CCC may
                  terminate the order without liability to HHH.

         (e)      If HHH terminates individual orders in whole or in part
                  because of CCC's failure to deliver, HHH's sole remedy shall
                  be to cancel the undelivered quantity of any individual order.

5.10     GOVERNING TERMS: Nothing contained in a purchase order or form for
         acceptance, confirmation or acknowledgment of purchase orders shall in
         any way modify the terms of purchase set forth herein or add any
         additional terms or conditions, unless the Parties indicate in writing
         their mutual agreement and intent to modify the terms of this

5.11     ENGINEERING CHANGES BY CCC: If CCC makes any Major Engineering Change
         to any Component Product, it will give written notice thereof to HHH in
         which it will supply a written description of the expected effect of
         the Engineering Change on such Component Product. Any notice of a Major
         Engineering Change shall be deemed to be an EOL Notice with respect to
         such Component Product, with the effect that HHH shall have the
         end-of-life purchase rights granted in Section 5.15. CCC will use
         commercially reasonable efforts to give HHH prompt notice of any Minor
         Engineering Changes.

5.12     DELIVERY DATES: CCC will make commercially reasonable efforts to
         deliver in accordance with these dates. CCC will give written notice to
         HHH if CCC determines that constraints have arisen that it make it
         likely that delivery of a particular shipment of Component Products
         will be significantly delayed.

5.13     FIRST ARTICLE ACCEPTANCE: Upon receipt of the first shipment of any
         particular Component Product, HHH has [***] to inspect the shipment and
         accept it ("Inspection Period"). If no written notice is received by
         CCC within [***] of receipt of the first shipment, HHH will have
         indicated that they have accepted such Component Product as is, and
         confirmed delivery of future shipments for the Component Products as
         is, and that the Component Products have passed the first article
         acceptance. During the Inspection Period, HHH will notify CCC in
         writing of any product deficiencies it finds. CCC will then promptly
         correct the Component Product deficiencies so identified by HHH. If CCC
         has not corrected the Component Product deficiencies within [***] after
         first notice to it by HHH, HHH may return such Component Product(s) (or
         portion thereof). CCC will promptly refund HHH all amounts paid for
         such Component Products.

5.14     COMPONENT PRODUCT SHORTAGES: Subject to compliance with applicable
         laws, in the event of Component Product shortages, for any reason
         whatsoever, CCC shall use

         commercially reasonable efforts to meet all of HHH's requirements for
         Component Products.

5.15     DISCONTINUATION OF COMPONENT PRODUCT: In the event that CCC determines
         to discontinue any Component Product, CCC shall give written notice of
         such determination to HHH (an "EOL Notice") and offer at such time to
         HHH an end-of-life right to purchase (the "EOL Purchase Right") such
         discontinued Component Product (a "Discontinued Component Product") on
         the following terms and conditions of this Section 5.15. The EOL
         Purchase Right shall consist of the right of HHH to order over a period
         of up to [***] from the date of the EOL Notice (the "EOL Period"), for
         delivery up to [***] from the date of order, such additional quantity
         of Discontinued Component Products as HHH may desire to purchase.

5.16     [***]: CCC agrees that [***] in such reasonable quantities as HHH may
         request and at reasonable and customary prices. [***].

5.17     [***]: HHH agrees that [***].

                              Term and Termination

6.1      TERM: The term of this Agreement shall be five (5) years beginning on
         the Effective Date, which term shall be automatically renewed at the
         end of such initial term on the anniversary date of the Effective Date
         for additional one (1) year renewal terms, unless terminated by either
         Party in writing at least ninety days (90) before the end of the

6.2      TERMINATION: CCC may terminate this Agreement if HHH fails to pay for
         any Component Products in accordance with the terms of this Agreement,
         or if HHH fails to comply with any material term or condition of this
         Agreement, in either case within [***] of written notice of such
         failure from CCC unless such failure is cured within such [***] period
         or, if such failure is not reasonably curable within such period and
         does not involve a failure to pay for any Component Products, HHH is
         using diligent efforts to cure such failure; provided that CCC in any
         event may terminate this Agreement if for any reason any such curable
         failure to comply has not been cured within [***] of such written
         notice of failure. Additionally, CCC may terminate this Agreement for
         cause immediately if HHH (a) files or has filed against it a petition
         in bankruptcy, (b) has a receiver appointed to handle its assets or
         affairs, or (c) makes or attempts to make an assignment for benefit of
         creditors. HHH may terminate this Agreement if CCC fails to comply with
         any material term or condition of this Agreement within [***] of
         written notice of such failure from HHH unless such failure is

         reason any such curable failure to comply has not been cured within
         [***] of such written notice of failure. Either Party's rights to
         terminate are in addition to any other rights that Party may have.

6.3      EFFECT OF TERMINATION OR EXPIRATION: Regardless of termination or
         expiration of this Agreement, HHH shall pay for all Component Products
         delivered or shipped and other then pending non-cancelable orders in
         accordance with Exhibit A and any other amounts due hereunder.

                         Warranties and Indemnification

7.1      WARRANTIES BY CCC:

         7.1.1    Intellectual Property Rights. CCC represents and warrants that
                  it has the corporate power and authority required to enter
                  into this Agreement and perform its obligations hereunder and
                  that, to its knowledge, no claims, actions or proceedings have
                  been brought alleging that the E4 Component Product nor any
                  technology to be incorporated in the E4 Component Product,
                  including without limitation CCC E4 Microcode, infringe any
                  third party copyright or patent or incorporates any
                  misappropriated trade secrets of any third party.

         7.1.2    Performance of CCC Microcode. Effective upon delivery of CCC
                  [***] or [***] to HHH that has been commercially released by
                  CCC in production form, and for a period of [***], or in the
                  case of the CCC E4 Microcode, the CCC E4 Tools and the [***]
                  from the Effective Date (such [***] being referred to as the
                  CCC Software Warranty Period), CCC warrants that such CCC
                  Licensed Software will perform substantially in accordance
                  with the published specifications in effect at the time of
                  shipment to HHH and will be free of any virus, worm or other
                  malicious code or any time limiting codes, authorization
                  strings, timers, lockouts or other means of disabling the use
                  thereof (collectively, "Disabling or Contaminated Code").
                  During the CCC Software Warranty Period, CCC shall, upon
                  written request of HHH, make reasonable efforts to correct any
                  reproducible Errors in the such CCC Licensed Software which
                  cause it not to perform substantially in accordance with its
                  specifications and documentation and to eliminate any
                  Disabling or Contaminated Code.

         7.1.3    PERFORMANCE OF COMPONENT PRODUCTS

         (a)      CCC warrants to HHH that the Component Products (other than
                  microcode) will be free from defects in materials and
                  workmanship and will comply with the applicable CCC
                  specifications in effect at the time of shipment to HHH in all
                  material respects for a period of one (1) year from shipment
                  (the "Warranty Period"), and that any associated microcode
                  will substantially conform during the

<PAGE>   18
                  Warranty Period to the applicable CCC specifications in effect
                  at the time of shipment to HHH. This limited warranty does not
                  cover the results of accidents, abuse, neglect, improper
                  testing, vandalism, acts of God, use contrary to
                  specifications or instructions, or repair or modification by
                  anyone other than CCC or CCC's authorized agents. CCC SHALL
                  HAVE NO OBLIGATION UNDER THIS WARRANTY AND MAKES NO
                  REPRESENTATION AS TO PRODUCTS WHICH HAVE BEEN MODIFIED BY HHH
                  OR HHH'S CUSTOMERS.

         (b)      If the Component Product does not conform to the foregoing
                  warranties, HHH may, at its own risk and expense, return the
                  allegedly defective Component Product directly to CCC during
                  the Warranty Period. HHH must first notify CCC in writing of
                  the alleged defect and request a return material authorization
                  ("RMA") number. Returned materials shall comply with CCC's RMA
                  policy, a copy of which is available to HHH upon request.
                  Within [***] of its receipt of the RMA number, HHH may ship
                  the allegedly defective Component Product directly to CCC, and
                  shall include a notation of the RMA number, sufficient
                  information to identify the original purchase order and a
                  brief statement explaining the alleged defect. Any Component
                  Products returned to CCC without an authorized RMA number may
                  be returned to HHH, freight collect. Upon receipt of the
                  Component Product, CCC, at its option, will repair or replace
                  the Component Product and ship the repaired or replaced
                  Component Product to HHH at CCC's expense and risk, or refund
                  the purchase price. If CCC determines that any returned
                  Component Product fully conforms to the applicable
                  specifications for that Component Product, CCC will return the
                  Component Product to HHH at HHH's expense and risk, along with
                  a written statement setting forth the basis for CCC's
                  conclusion that the returned Component Product was not
                  defective, and HHH agrees to pay CCC's reasonable costs of
                  handling and testing. The right to return Component Products
                  is extended only to HHH, and CCC will not accept returns
                  directly from HHH's customers or users of HHH's products. The
                  right to return Component Products shall not apply to any
                  modified Component Products.

         7.1.4    Exceptions. The provisions of this Section 7.1 shall not apply
                  to any Error or defect CCC reasonably substantiates was caused
                  by (a) any modifications to the CCC Licensed Software or
                  Component Product made by HHH; (b) operation of the CCC
                  Licensed Software or Component Product with any software,
                  hardware or other equipment not provided by CCC; or (c) misuse
                  of the CCC Licensed Software or Component Product.

         7.1.5    Disclaimer of Warranties. EXCEPT AS EXPRESSLY PROVIDED IN THIS
                  SECTION 7.1, THE CCC LICENSED SOFTWARE AND COMPONENT PRODUCTS
                  ARE BEING PROVIDED "AS IS" AND CCC MAKES NO, AND CCC EXPRESSLY
                  DISCLAIMS ALL, OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
                  WITHOUT LIMITATION, WARRANTIES OF MERCHANTABILITY OR FITNESS
                  FOR A PARTICULAR PURPOSE OR NON-INFRINGEMENT WITH REGARD TO

                  SERVICE OR RELATED MATERIALS PROVIDED UNDER THIS AGREEMENT.

7.2      INDEMNIFICATION: Except as expressly limited below, CCC agrees to
         indemnify HHH, hold HHH harmless, and defend HHH and its officers,
         directors, agents, and employees, at CCC's expense, from any and all
         third party claims resulting from any alleged infringement of patents
         or copyrights, or the misuse of third party trade secrets by the CCC
         Licensed Software or Component provided under this Agreement and used
         with in the scope of this Agreement, provided HHH gives CCC prompt
         notice of any such claims and authorizes CCC to settle or defend such
         claims and assists CCC in so doing (at CCC's expense) upon request by
         CCC. Should HHH be enjoined from selling or using the CCC Licensed
         Software as a result of such claim, CCC will use best efforts to
         either, at its sole option, (1) procure for HHH the right to use or
         sell the CCC Licensed Software; (2) modify the CCC Licensed Software so
         that it becomes non-infringing, while continuing to meet the applicable
         published specifications in effect at the time of shipment; or (3) upon
         return of the CCC Licensed Software to CCC, provide to HHH a
         non-infringing substitute meeting the functional specifications of the
         CCC Licensed Software. Should HHH be enjoined from selling or using the
         any Component Product as a result of such claim, CCC will, at its sole
         option, either (1) procure for HHH the right to use or sell the
         Component Product; (2) modify the Component Product so that it becomes
         non-infringing, while continuing to meet the applicable published
         specifications in effect at the time of shipment; (3) upon return of
         the Component Product to CCC, provide to HHH a non-infringing
         substitute meeting the functional specifications of the Component
         Product; or (4) authorize the return of the Component Product to CCC

         Product.

         THIS INDEMNITY SHALL NOT COVER ANY CLAIM:

         (i)      for patent infringement based upon any combination of the CCC

                  product or products, whether or not supplied by CCC;

         (ii)     for infringement of any proprietary rights arising in whole or
                  in part from changes made to the CCC Licensed Software or

                  Licensed Software or Component Product that was designed by or
                  requested by HHH on a custom basis;

         (iii)    against HHH, or any claim against CCC by HHH, where (1) the
                  use of a Component Product is not a use specified for the
                  Component Product in CCC's documentation and (2) such claim is
                  based upon contributory infringement or inducement of
                  infringement either by HHH or by CCC; and

         (iv)     for the infringement of any proprietary rights of a third
                  party arising out of CCC's compliance with any technical or
                  commercial standards adopted by international organizations or
                  consortia such as the International Standards Organization,
                  the International Electrotechnical Commission, the
                  International Telecommunications Union, or any other industry

                  DVD, Dolby, DTS, Macrovision, and/or H.261. HHH shall be
                  solely responsible for obtaining all necessary licenses under
                  such proprietary rights.

         HHH shall indemnify CCC and shall hold CCC harmless from and defend CCC

         such claim provided that: (1) HHH is notified promptly in writing by
         CCC of the claim or suit and (2) at HHH's request, HHH is given control
         of the suit and CCC provides all requested reasonable assistance (at
         HHH's expense).

7.3      REMEDIES: The provision of corrections or replacements by CCC pursuant
         to Sections 7.1.2 and 7.1.3 of this Agreement shall be HHH's sole and
         exclusive remedy with respect to any breach of the warranty set forth
         in Section 7.1.2 or 7.1.3.

7.4      WARRANTIES AND REPRESENTATIONS BY HHH:

                  it has the corporate power and authority required to enter
                  into this Agreement and perform its obligations hereunder and
                  that, to its knowledge, no claims, actions or proceedings have
                  been brought alleging that the HHH E4 Microcode infringes any
                  third party copyright or patent or incorporates any
                  misappropriated trade secrets of any third party.

         7.4.2    Performance of HHH Microcode. For a period of [***] after the

                  production form will perform substantially in accordance with
                  the published specifications in effect on the Effective Date
                  and will be free of any Disabling or Contaminated Code. During
                  the HHH Warranty Period, HHH shall, upon written request of
                  CCC, make reasonable efforts to correct any reproducible
                  Errors in the such HHH Licensed Software which cause it not to
                  perform substantially in accordance with its specifications or
                  eliminate the Disabling or Contaminated Code.

         7.4.3    Exceptions. The provisions of this Section 7.4 shall not apply

                  CCC; (b) operation of the HHH Licensed Software with any
                  software, hardware or other equipment not provided by HHH; or
                  (c) misuse of the HHH Licensed Software.

         such claims and authorizes HHH to settle or defend such claims and
         assists HHH in so doing (at HHH's expense) upon request by HHH. Should
         CCC be enjoined from selling or using the HHH Licensed Software as a
         result of such claim, HHH will use reasonable efforts to either, at its
         sole option, (1) procure for CCC the right to use or sell the HHH
         Licensed Software; (2) modify the HHH Licensed Software so that it
         becomes non-infringing; or (3) upon return of the HHH Licensed Software
         to HHH, provide to CCC a non-infringing substitute meeting the
         functional specifications of the HHH Licensed Software.

         THIS INDEMNITY SHALL NOT COVER ANY CLAIM:

         (i)      for patent infringement based upon any combination of the HHH
                  Licensed Software with any other product or products, whether
                  or not supplied by HHH;

                  designed by or requested by CCC on a custom basis;

         (iii)    against CCC, or any claim against HHH by CCC, where such claim
                  is based upon contributory infringement or inducement of
                  infringement either by CCC or by HHH;

         (iv)     for patent infringement claims against CCC brought by a third
                  party as a counterclaim in a litigation first instigated by
                  CCC against the third party; and

         (v)      for the infringement of any proprietary rights of a third
                  party arising out of HHH's compliance with any technical or
                  commercial standards adopted by international organizations or
                  consortia such as the International Standards Organization,
                  the International Electrotechnical Commission, the
                  International Telecommunications Union, or any other industry
                  standards, some of which are proprietary to third parties,
                  including, without limitation, JPEG, MPEG, VIDEO CD, DVD,
                  Dolby, DTS, Macrovision, and/or H.261. CCC shall be solely
                  responsible for obtaining all necessary licenses under such
                  proprietary rights.

         CCC shall indemnify HHH and shall hold HHH harmless from and defend HHH
         against any claims of infringement against HHH of the kind enumerated
         in Sections 7(a) (i) and (ii) above. HHH shall pay all costs including
         attorneys' fees and damages finally awarded in any suit asserting any
         such claim provided that: (1) CCC is notified promptly in writing by
         HHH of the claim or suit and (2) at CCC's request, CCC is given control
         of the suit and HHH provides all requested reasonable assistance (at
         CCC's expense).

7.6      REMEDIES: The provision of corrections or replacements by HHH pursuant
         to Sections 7.4.2 shall be CCC's sole and exclusive remedy with respect
         to any breach of the warranty set forth in Section 7.4.2.

         THAN FOR BREACH OF ANY OF THE CONFIDENTIALITY OBLIGATIONS OF SECTION 8

         SHALL HAVE ANY LIABILITY FOR ANY INDIRECT OR SPECULATIVE DAMAGES
         (INCLUDING, WITHOUT LIMITING THE FOREGOING, CONSEQUENTIAL, INCIDENTAL
         AND SPECIAL DAMAGES), INCLUDING, BUT NOT LIMITED TO, LOSS OF USE,
         BUSINESS INTERRUPTIONS, AND LOSS OF PROFITS, IRRESPECTIVE OF WHETHER
         THE PARTY HAS ADVANCE NOTICE OF THE POSSIBILITY OF ANY SUCH DAMAGES.
         NOTWITHSTANDING THE FOREGOING, THE TOTAL LIABILITY OF EITHER PARTY TO
         THE OTHER WITH RESPECT TO ANY CLAIM ASSERTED AGAINST SUCH PARTY BY THE
         OTHER PARTY UNDER THIS AGREEMENT, EXCLUDING (i) HHH'S LIABILITY TO CCC
         FOR PAYMENT OF THE PURCHASE PRICE OF ANY COMPONENT PRODUCTS PURCHASED
         BY HHH HEREUNDER, (ii) ANY LIABILITY OF EITHER PARTY FOR BREACH OF ANY
         OF THE CONFIDENTIALITY OBLIGATIONS OF SECTION 8 AND (iii) ANY
         INDEMNIFICATION LIABILITY OF A PARTY UNDER SECTION 7.2, 7.5 OR 7.8,
         SHALL NOT EXCEED THE AGGREGATE AMOUNT HAVING ACTUALLY BEEN PAID BY HHH
         TO CCC UNDER SECTION 5 OF THIS AGREEMENT FOR THE PRODUCTS TO WHICH THE
         CLAIM RELATES. THE PARTIES ACKNOWLEDGE THAT THESE LIMITATIONS ON
         POTENTIAL LIABILITIES WERE AN ESSENTIAL ELEMENT IN SETTING
         CONSIDERATION UNDER THIS AGREEMENT.

7.8      COMPONENT PRODUCT LIABILITY:

         7.8.1    Indemnification by HHH. In the event that CCC is named in a
                  personal injury or product liability suit arising out of use
                  of the Component Products by HHH under this Agreement, HHH
                  will defend or settle such suit to the extent the claims
                  asserted in such suit arise from (a) CCC's compliance with
                  HHH's designs, specifications, or instruction, (b)
                  modification of the Component Products by a Party other than
                  CCC after delivery by CCC made without the prior written
                  consent of CCC, or (c) the use of the Component Products, or
                  any part thereof, in combination with any other product. In
                  addition, HHH will pay all damages and costs finally awarded
                  against CCC in any such suit, but HHH will not be responsible
                  for any costs, expenses, or compromise incurred or made by CCC
                  without HHH's prior written consent, which consent shall not
                  be unreasonably withheld. Notwithstanding the foregoing, in no
                  event will HHH have any responsibility under this Section
                  7.8.1 in respect of claims that are proximately caused by the
                  willful misconduct or gross negligence of CCC.

         7.8.2    Indemnification by CCC. In the event that HHH is named in a
                  personal injury or product liability suit arising out of use
                  of the Component Products furnished by

                                       22
<PAGE>   23
                  CCC under this Agreement standing alone and not in combination
                  with any HHH Component Product or other product, and such suit
                  is not a suit as to which HHH is obligated to defend and
                  indemnify CCC pursuant to Section 7.8.1, CCC will defend or
                  settle such suit and will pay all damages and costs finally
                  awarded against HHH in such suit, but CCC will not be
                  responsible for any costs, expenses, or compromise incurred or
                  made by HHH without CCC's prior written consent, which consent
                  shall not be unreasonably withheld. Notwithstanding the
                  foregoing, in no event will CCC have any responsibility under
                  this Section 7.8.2 in respect of claims that are proximately
                  caused by the willful misconduct or gross negligence of HHH.

                                    Section 8

                                 Confidentiality

8.1      CONFIDENTIALLY OBLIGATIONS: Either party (the "Disclosing Party") may
         from time to time disclose Confidential Information to the other party
         (the "Recipient"). "Confidential Information" is all nonpublic
         information concerning the business, technology, internal structure and
         strategies of the Disclosing Party which is conveyed to the Recipient
         orally or in tangible form and is either marked as "confidential" or
         which do due to the circumstances surrounding its disclosure, such
         information would be reasonably construed as "confidential". During the
         term of this Agreement and for a period of [***] thereafter, Recipient
         will keep in confidence and trust and will not disclose or disseminate,
         or permit any employee, agent or other person working under Recipient's
         direction to disclose or disseminate, the existence, source, content or
         substance of any Confidential Information to any other person.
         Recipient shall use Confidential Information of the Disclosing Party
         only as necessary for the performance of this Agreement. Recipient will
         employ at least the same methods and degree of care, but no less than a
         reasonable degree of care, to prevent disclosure of the Confidential
         Information as Recipient employs with respect to its own confidential
         trade secrets and proprietary information. Recipient's employees and
         independent contractors will be given access to the Confidential
         Information only on a need-to-know basis, and only if they have
         executed a form of non-disclosure agreement with Recipient which
         imposes a duty to maintain the confidentiality of information
         identified or described as confidential by Recipient and after
         Recipient has expressly informed them of the confidential nature of the
         Confidential Information.

8.2      PERMITTED DISCLOSURES. The commitments in this Article 8 will not
         impose any obligations on Recipient with respect to any portion of the
         received information which: (i) is now generally known or available or
         which, hereafter through no act or failure to act on the part of
         Recipient, becomes generally known or available; (ii) is rightfully
         known to Recipient at the time of receiving such information; (iii) is
         furnished to Recipient by a third party without restriction on
         disclosure and without Recipient having actual notice or reason to know
         that the third party lacks authority to so furnish the information;
         (iv) is independently developed by Recipient or is of general
         application which may be retained in the unaided memory of an
         individual; or (v) is required to be disclosed by operation of

         law or by an instrumentality of the government, including but not
         limited to any court, tribunal or administrative agency.

8.3      CONFIDENTIALITY OF AGREEMENT: The existence, terms, and conditions of
         this Agreement are confidential and neither Party may make any
         disclosures regarding this Agreement without the express prior written
         consent of the other, with the following exceptions:

                  a.       subject to Section 8.4 below, as otherwise may be
                           required by law or legal process, to legal and
                           financial advisors in their capacity of advising a
                           Party in such matters; or

                  b.       in confidence to its legal counsel, accountants,
                           banks and financing sources and their advisors solely
                           in connection with complying with financial
                           transactions.

8.4      COMPELLED DISCLOSURE: In the event that any Party hereto receives a
         request to disclose all or any part of any confidential information
         under the terms of a subpoena, order, civil investigative demand or
         similar process issued by a court of competent jurisdiction or by
         another Governmental Authority, such Party agrees to: (i) promptly
         notify the Party to whom such confidential information relates of the
         existence, terms and circumstances surrounding such request, (ii)
         consult with such Party to whom the information relates on the
         advisability of taking legally available steps to resist or narrow such
         request and (iii) if disclosure of such information is required,
         furnish only that portion of the confidential information that, in the
         opinion of counsel to the Party who has received the request, such
         Party is legally compelled to disclose and advise the Party to whom
         such confidential information relates as far in advance of such
         disclosure as possible so that such Party to whom the confidential
         information relates may seek an appropriate protective order or other
         reliable assurance that confidential treatment will be accorded such
         confidential information. In any event, the Party who receives the
         request shall not oppose actions by the Party to whom the confidential
         information relates to obtain an appropriate protective order or other
         reliable assurance that confidential treatment will be accorded such
         confidential information.

8.5      THIRD-PARTY DISCLOSURE: Each Party agrees that, to the extent it is
         permitted to disclose Confidential Information to a Third-party or
         Affiliate (other than a Party), it shall do so pursuant to a written
         non-disclosure agreement containing terms at least as protective of
         Confidential Information as those set forth in this Agreement.

8.6      REMEDIES: Unauthorized use by a Receiving Party of the Disclosing
         Party's Confidential Information will result in irreparable harm to the
         Disclosing Party. Therefore, if a Party breaches any of its obligations
         with respect to confidentiality and unauthorized use of Confidential
         Information hereunder, the Disclosing Party, in addition to any rights
         and remedies it may have, shall be entitled to seek equitable,
         including injunctive, relief to protect its Confidential Information.

                               Miscellaneous Terms

9.1      CONFLICTS: In the event of a conflict between this Agreement and any
         other document related to the subject matter of this Agreement, or the
         body of this Agreement and any of the Exhibits to this Agreement, the
         terms of this Agreement, or the body of this Agreement as the case may
         be, shall govern.

9.2      FORCE MAJEURE: No Party will be liable for any failure to perform due
         to unforeseen circumstances or causes beyond its reasonable control,
         including, but not limited to, acts of God, war, riot, embargoes, acts
         of civil or military authorities, fire, flood, accident or strikes. In
         the event of force majeure, time for delivery or other performance will
         be extended for a period equal to the duration of the delay caused
         thereby.

9.3      EXPORT: No Party shall export, either directly or indirectly, any
         Component Products or system incorporating such Component Products, in
         whole or in part, without first obtaining any required license or other
         approval from the U. S. Department of Commerce or any other agency or
         department of the United States Government. In the event any Component
         Products are exported from the United States or re-exported from a
         foreign destination by HHH, its distributors or end users, HHH shall
         ensure that the distribution and export/re-export of the Component
         Product is in compliance with all laws, regulations, orders, or other
         restrictions of the U.S. Export Administration Regulations. HHH agrees
         that neither it nor any of its subsidiaries will export/re-export any
         technical data, process, product, or service, directly or indirectly,
         to any country for which the United States government or any agency
         thereof requires an export license, other governmental approval, or

9.6      ASSIGNMENT:

         a.       This Agreement and any licenses granted herein are not
                  assignable by HHH, in whole or in part, without the prior
                  written consent of CCC except to any wholly-owned subsidiary
                  of HHH or in connection with a merger or other change of
                  control of HHH or a sale of all of substantially all of the
                  assets of HHH and except as provided in Section 9.6(c);
                  provided that any such permitted assignee shall agree in
                  writing to be bound by all of the terms and conditions hereof.
                  Any such purported assignment or transfer in violation of the
                  foregoing requirements of this Section 9.6(a) shall be deemed
                  a breach of this Agreement and shall be null and void.
                  Notwithstanding the foregoing, if HHH merges with another
                  entity or a change of control of HHH otherwise occurs during
                  the term of this Agreement, (i) any Person with which HHH so
                  merges or that otherwise acquires control of HHH (an "HHH
                  Acquiring Party") shall agree in writing to be bound by the
                  provisions of Section 8 hereof; and (ii) the licenses granted
                  by CCC of CCC Licensed Software thereafter shall be exercised
                  only with respect to products of HHH then commercially
                  released or under development by HHH, and any successor or
                  replacement products, but not any products theretofore
                  commercially released by the HHH Acquiring Party.

         b.       This Agreement and any licenses granted herein are not
                  assignable by CCC, in whole or in part, without the prior
                  written consent of HHH except to any wholly-owned subsidiary
                  or to the successor of the CCC Semiconductor Business pursuant
                  to the disposition thereof pursuant to the Merger Agreement
                  (the "Semiconductor Business Successor") or in connection with
                  a merger or other change of control of such successor or a
                  sale of all of substantially all of the assets of the
                  Semiconductor Business; provided that any such permitted
                  assignee shall

                                       27
<PAGE>   28
                  agree in writing to be bound by all of the terms and
                  conditions hereof. Any such purported assignment or transfer
                  in violation of the foregoing requirements of this Section
                  9.6(b) shall be deemed a breach of this Agreement and shall be
                  null and void. Notwithstanding the foregoing, if the
                  Semiconductor Business Successor merges with another entity or
                  a change of control of the Semiconductor Business Successor
                  otherwise occurs during the term of this Agreement, (i) any
                  Person with which the Semiconductor Business Successor so
                  merges or that otherwise acquires control of the Semiconductor
                  Business Successor (an "SBS Acquiring Party") shall agree in
                  writing to be bound by the provisions of Section 8 hereof; and
                  (ii) the licenses granted by HHH of HHH Licensed Software
                  thereafter shall be exercised only with respect to products of
                  the Semiconductor Business Successor then commercially
                  released or under development by Semiconductor Business
                  Successor, and any successor or replacement products, but not
                  any products theretofore commercially released by the SBS
                  Acquiring Party.

         c.       Notwithstanding the foregoing, CCC agrees and acknowledges
                  that HHH may designate to up to [***] different subcontract
                  manufacturers of HHH products (each a "Designated HHH
                  Subcontractor") HHH's rights and benefits under this Agreement
                  with respect to the purchase of Semiconductor Products and the
                  licensing of CCC E4 Microcode or CCC [***] in object code from
                  CCC in connection therewith, and CCC agrees to sell Component
                  Products and license such CCC Licensed Software to each such
                  Designated HHH Subcontractor as though such Designated HHH
                  Subcontractor on all the same terms and conditions as would be
                  applicable if such Component Products were sold and such CCC
                  Licensed Software were licensed to HHH pursuant to the terms
                  and conditions hereof (it being agreed and acknowledged that
                  each such Designated HHH Subcontractor shall agree to be bound
                  by the terms and conditions hereof applicable thereto and
                  shall be liable directly to CCC for the performance of any
                  obligations of such Designated HHH Subcontractor related to
                  the purchase of Component Products and licensing such CCC
                  Licensed Software by such Designated HHH Subcontractor);
                  provided that such Component Products and CCC Licensed
                  Software shall be used and exploited by such Designated HHH
                  Subcontractor only in connection with Harmonic products and
                  such Designated HHH Subcontractor shall be prohibited from
                  using any such CCC Licensed Software with any semiconductor
                  component other than a Component Product.

9.7      RELATIONSHIP BETWEEN THE PARTIES: In all matters relating to this
         Agreement, HHH and CCC shall act as independent contractors. Neither
         Party will represent that it has any authority to assume or create any
         obligation, expressed or implied, on behalf of the other Party, or to
         represent the other Party as agent, employee, or in any other capacity.
         Neither Party shall have any obligation, expressed or implied, except
         as expressly set forth herein.

9.8      INTERPRETATION: This Agreement, including any exhibits, addenda,
         schedules, and amendments, has been negotiated at arm's length and
         between persons sophisticated and knowledgeable in the matters dealt
         with in this Agreement. Each Party has been represented by experienced
         and knowledgeable legal counsel. Accordingly, any rule of

    treatment request filed with the Securities and Exchange Commission. Such
    portions have been provided separately to the Commission.

                                       28

         law or legal decision that would require interpretation of any
         ambiguities in this Agreement against the Party that has drafted it is
         not applicable and is waived.

9.9      ENTIRE AGREEMENT: This Agreement sets forth the entire Agreement
         between the Parties and supersedes prior and contemporaneous proposals,
         agreements, and representations between them, whether written or oral,
         relating to the subject matter contained herein. This Agreement may be
         changed only if agreed to in writing and signed by an authorized
         signatory of each Party.

9.10     REMEDIES: All rights and remedies, whether conferred hereunder or by
         any other instrument or law, will be cumulative and may be exercised
         singularly or concurrently. The failure of any Party to enforce any of
         the provisions hereof shall not be construed to be a waiver of the
         right of such Party thereafter to enforce such provisions.

9.11     SEVERABILITY: The terms and conditions stated herein are declared to be
         severable. If any provision or provisions of this Agreement, or the
         application thereof to any Person, place or circumstance, shall be held
         by a court of competent jurisdiction to be invalid, unenforceable or
         void, the remainder of this Agreement and such provisions as applied to
         other Persons, places and circumstances shall remain in full force and
         effect.

9.12     COUNTERPARTS: This Agreement may be executed in several counterparts,
         each of which shall be deemed an original, but all of which together
         shall constitute one and the same instrument.

9.13     INJUNCTIVE RELIEF: The Parties agree that preliminary injunctive or
         other equitable relief may be a necessary and proper remedy in the
         event of a breach of this Agreement in violation of either Party's
         Intellectual Property rights. The Parties further agree that in the
         event such equitable relief is granted in the United States, they will
         not object to courts in other jurisdictions granting provisional
         remedies enforcing such U.S. judgments.

9.14     TAX: HHH is responsible for all taxes on transactions between CCC and
         HHH under this Agreement other than taxes based on CCC's income. All
         payments shall be made free and clear without deduction for any and all
         present and future taxes imposed by any taxing authority. In the event
         that HHH is prohibited by law from making such payments unless such
         deductions are made or withheld therefrom, then HHH shall pay such
         additional amounts as are necessary in order that the net amounts
         received by CCC, after such deduction or withholding, equal the amounts
         which would have been received if such deduction or withholding had not
         occurred. HHH shall promptly furnish CCC with a copy of an official tax
         receipt or other appropriate evidence of any taxes imposed on payments
         made under this Agreement, including taxes on any additional amounts
         paid. In cases other than taxes referred to above, including but not
         limited to sales and use taxes, stamp taxes, value added taxes,
         property taxes, and other taxes or duties imposed by any taxing
         authority on or with respect to this Agreement, the costs of such taxes
         or duties shall be borne by HHH. In the event that such taxes or duties
         are legally imposed initially on CCC or CCC is later assessed by any
         taxing authority, then CCC will be promptly reimbursed by HHH for such
         taxes or duties plus any interest and penalties suffered by CCC. This
         clause shall survive the termination of the Agreement.

9.15     GOVERNING LAW: Any claims arising under or relating to this Agreement
         shall be governed by the internal substantive laws of the State of
         Delaware or federal courts located in Delaware, without regard to
         principles of choice or conflict of laws.

9.16     JURISDICTION; WAIVER OF JURY TRIAL:

         (a)      The Parties irrevocably submit to the jurisdiction of the
                  courts of the State of Delaware and the Federal courts of the
                  United States of America located in the State of Delaware
                  solely in respect of the interpretation and enforcement of the
                  provisions of this Agreement and of the documents referred to
                  in this Agreement, and in respect of the transactions
                  contemplated hereby, and hereby waive, and agree not to
                  assert, as a defense in any Proceeding for the interpretation
                  or enforcement hereof or of any such document, that it is not
                  subject thereto or that such Proceeding may not be brought or
                  is not maintainable in said courts or that the venue thereof
                  may not be appropriate or that this Agreement or any such
                  document may not be enforced in or by such courts, and the
                  Parties irrevocably agree that all claims with respect to such
                  Proceeding shall be heard and determined in such a Delaware
                  State or Federal court. The Parties consent to and grant any
                  such court jurisdiction over the person of such Parties and
                  over the subject matter of such dispute and agree that mailing
                  of process or other papers in connection with any such action
                  or proceeding in the manner provided in Section 9.4 or in such
                  other manner as may be permitted by Applicable Law, shall be
                  valid and sufficient service thereof. This provision is meant
                  to comply with 6 Del. C. Section 2708(a).

         (b)      The Parties agree that irreparable damage could occur and that
                  the Parties would not have any adequate remedy at law 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 seek an injunction or injunctions to
                  prevent breaches of this Agreement and to enforce specifically
                  the terms and provisions of this Agreement in any Federal
                  court located in the State of Delaware or in Delaware state
                  court, this being in addition to any other remedy to which
                  they are entitled at law or in equity.

         (c)      EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH
                  MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE
                  COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH
                  PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT
                  SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
                  LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING
                  TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS
                  AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO
                  REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS
                  REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY
                  WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
                  FOREGOING WAIVER, (ii) EACH SUCH PARTY

                                       30
<PAGE>   31
                  UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS
                  WAIVER, (iii) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY,
                  AND (iv) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS
                  AGREEMENT BY, AMONG OTHER THINGS, THE WAIVERS AND
                  CERTIFICATIONS IN THIS SECTION 9.16.

9.17     MEANING OF INCLUDE AND INCLUDING: Whenever in this Agreement the word
         "include" or "including" is used, it shall be deemed to mean "include,
         without limitation" or "including, without limitation," as the case may
         be, and the language following "include" or "including" shall not be
         deemed to set forth an exhaustive list.

9.18     AUDIT: CCC shall have the right, not more than once in any calendar
         year during the term of this Agreement and upon reasonable notice and
         during normal business hours, to audit the sales records of HHH for
         purposes of determining whether the Component Products that are sold as
         chipsets have been broken into separate chips and sold as separate
         products by HHH, thereby entitling CCC to the higher purchase price
         that would have been payable by HHH if separate chips originally were
         purchased by HHH rather than chipsets. If the amount of the
         underpayment discovered as a result of such audit is greater that [***]
         of the amount paid by CCC for the chipsets that were purchased by HHH
         during the period subject to audit, HHH shall reimburse CCC the
         reasonable out of pocket cost incurred by CCC in connection with such
         audit. HHH shall promptly pay any discrepancy that is discovered as a
         result of any such audit.

9.19     EFFECTIVENESS: This Agreement shall become effective upon the
         occurrence of the Effective Date and shall not otherwise have any force
         and effect.
