<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Item&nbsp;6. Indemnification of Directors and Officers.</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Reference is made to Section&nbsp;102(b)(7) of the Delaware General Corporation Law (the &#147;DGCL&#148;), which
enables a corporation in its original certificate of incorporation or an amendment to its
certificate of incorporation to eliminate or limit the personal liability of a director for
monetary damages for violations of the director&#146;s fiduciary duty, except (1)&nbsp;for any breach of a
director&#146;s duty of loyalty to the corporation or its stockholders, (2)&nbsp;for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of law, (3)&nbsp;pursuant to
Section&nbsp;174 of the DGCL, providing for liability of directors for unlawful payment of dividends or
unlawful stock purchases or redemption, or (4)&nbsp;for any transaction from which a director derived an
improper personal benefit.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Reference is also made to Section&nbsp;145 of the DGCL which provides that a corporation may indemnify
any persons, including officers and directors, who are, or are threatened to be made, parties to
any threatened, pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, other than an action by or in the right of the corporation, by
reason of the fact that the person was an officer, director, employee or agent of the corporation,
or is or was serving at the request of the corporation or other enterprise. The indemnity may
include expenses, including attorneys&#146; fees, judgments, fines and amounts paid in settlement
actually and reasonably incurred by the person in connection with the action, suit or proceeding,
provided the officer, director, employee or agent acted in good faith and in a manner he reasonably
believed to be in or not opposed to the corporation&#146;s best interests and, for a criminal
proceeding, had no reasonable cause to believe that his conduct was unlawful. A Delaware
corporation may indemnify officers and directors in an action by or in the right of the corporation
under the same conditions, except that no indemnification is permitted without judicial approval if
the officer or director is adjudged to be liable to the corporation. Where an officer or director
is successful on the merits or otherwise in the defense of any action referred to above, the
corporation must indemnify him against the expenses, including attorneys&#146; fees, which the officer
or director actually and reasonably incurred.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Amended and Restated Certificate of Incorporation of the Registrant and the Amended and
Restated Bylaws of the Registrant provide for the indemnification of officers and directors to the
fullest extent permitted by applicable law.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In addition, the Registrant has entered into agreements with its officers and directors that
provide for their indemnification with respect to certain matters, in addition to indemnification
provided for in its Amended and Restated Bylaws. These agreements, among other things, indemnify
the Registrant&#146;s officers and directors for certain expenses (including attorneys&#146; fees),
judgments, fines and settlement amounts incurred by any such person in any action or proceeding,
including any action by or in the right of the Registrant, arising out of such person&#146;s services as
an officer or director of the Registrant, any subsidiary of the Registrant or any other company or
enterprise to which the person provides services at the Registrant&#146;s request. The Registrant also
maintains an insurance policy insuring the Registrant&#146;s officers and directors against liability
for certain acts and omissions while acting in their official capacities.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;To include any prospectus required by Section&nbsp;10(a)(3) of the Securities Act;
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;To reflect in the prospectus any facts or events arising after the effective date of this
Registration Statement (or the most recent post-effective amendment thereof) which, individually or
in aggregate, represent a fundamental change in the information set forth in this Registration
Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered
(if the total dollar value of securities offered would not exceed that which is registered) and any
deviation from the low or high end of the estimated maximum range may be reflected in the form of
prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in
volume and price represent no more than 20&nbsp;percent change in the maximum aggregate offering price
set forth in &#147;Calculation of Registration Fee&#148; table in the effective registration statement;
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;To include any material information with respect to the plan of distribution not

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)&nbsp;That, for the purpose of determining any liability under the Securities Act, each such

the initial bona fide offering thereof.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&nbsp;To remove from registration by means of a post-effective amendment any of the securities

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The undersigned Registrant hereby undertakes that, for purposes of determining any liability

or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit
plan&#146;s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the Securities Act may be permitted
to directors, officers and controlling persons of the Registrant pursuant to the Registrant&#146;s
Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws, indemnification
agreements, or otherwise, the Registrant has been advised that in the opinion of the SEC such
indemnification is against public policy as expressed in the Securities 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 Securities Act and will be
governed by the final adjudication of such issue.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We have examined the registration statement on Form S-8 filed by Harmonic Inc. (&#147;you&#148; or the
&#147;Company&#148;) with the Securities and Exchange Commission on August 8, 2006 (the &#147;Registration
Statement&#148;), in connection with the registration under the Securities Act of 1933, as amended, of
2,000,000 shares of the Company&#146;s common stock, par value $0.001 per share (&#147;Common Stock&#148;), under
the Company&#146;s 2002 Employee Stock Purchase Plan, as amended, and 300,000 shares of Common Stock under the
Company&#146;s 2002 Director Option Plan, as amended. Such shares of Common Stock are referred to herein as the
&#147;Shares,&#148; and such plans are referred to herein as the &#147;Plans.&#148; As your counsel in connection with
this transaction, we have examined the proceedings taken and are familiar with the proceedings
proposed to be taken by you in connection with the issuance and sale of the Shares pursuant to the
Plans.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">It is our opinion that, when issued and sold in the manner described in the Plans and pursuant to
the agreements which accompany each grant under the Plans, the shares will be legally and validly
issued, fully paid and non-assessable.
