                            ------------------------

                   INFORMATION CONCERNING SOLICITATION VOTING

GENERAL

     The enclosed Proxy is solicited on behalf of the Board of Directors of
Harmonic Inc., a Delaware corporation (the "Company"), for use at the Annual
Meeting of Stockholders (the "Annual Meeting") to be held June 18, 2001 at 8:00
a.m., Pacific Time, or at any adjournment thereof, for the purposes set forth
herein and in the accompanying Notice of Annual Meeting of Stockholders. The
Annual Meeting will be held at The Westin Hotel, 5101 Great America Parkway,
Santa Clara, California, 95054. The telephone number of the Company's principal
offices is (408) 542-2500.

     These proxy solicitation materials and the Company's Annual Report to
Stockholders for the year ended December 31, 2000, including financial
statements, were mailed on or about May 15, 2001 to all stockholders entitled to
vote at the meeting.

RECORD DATE AND VOTING SECURITIES

     Stockholders of record at the close of business on April 20, 2001 (the
"Record Date") are entitled to notice of and to vote at the meeting. At the
Record Date, 58,216,500 shares of the Company's Common Stock, $0.001 par value
per share, were issued and outstanding.

REVOCABILITY OF PROXIES

     Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before its use by delivering to the Secretary of the
Company a written notice of revocation or a duly executed proxy bearing a later
date or by attending the meeting and voting in person.

VOTING AND SOLICITATION

     Each stockholder is entitled to one vote for each share of Common Stock on
all matters presented at the Annual Meeting. Stockholders do not have the right
to cumulate their votes in the election of directors.

     The Company will bear the cost of soliciting proxies. In addition, the
Company may reimburse brokerage firms and other persons representing beneficial
owners of shares for their expenses in forwarding solicitation material to such
beneficial owners. Solicitation of proxies by mail may be supplemented by
telephone, telegram, facsimile or personal solicitation by directors, officers
or employees of the Company. No additional compensation will be paid to such
persons for such services.

QUORUM; ABSTENTIONS; BROKER NON-VOTES

     The required quorum for the transaction of business at the Annual Meeting
is a majority of the votes eligible to be cast by holders of shares of Common
Stock issued and outstanding on the Record Date. Shares that are voted "FOR,"
"AGAINST," "WITHHELD" or "ABSTAIN" are treated as being present at the meeting
for purposes of establishing a quorum and are also treated as shares entitled to
vote at the Annual Meeting (the "Votes Cast") with respect to such matter.

     While there is no definitive statutory or case law authority in Delaware as
to the proper treatment of abstentions, the Company believes that abstentions
should be counted for purposes of determining both (i) the presence or absence
of a quorum for the transaction of business and (ii) the total number of Votes

                                        1
   4

Cast with respect to a proposal (other than the election of directors). In the
absence of controlling precedent to the contrary, the Company intends to treat
abstentions in this manner. Accordingly, abstentions will have the same effect
as a vote against the proposal.

     The Delaware Supreme Court has held that, while broker non-votes should be
counted for purposes of determining the presence or absence of a quorum for the
transaction of business, broker non-votes should not be counted for purposes of
determining the number of Votes Cast with respect to the particular proposal on
which the broker has expressly not voted. The Company intends to treat broker
non-votes in a similar manner. Thus, a broker non-vote will not affect the
outcome of the voting on a proposal.

DEADLINE FOR RECEIPT OF STOCKHOLDER PROPOSALS

     Proposals of stockholders of the Company that are intended to be presented
by such stockholders at the Company's 2002 annual meeting and that stockholders
desire to have included in the Company's proxy materials relating to such
meeting must be received by the Company no later than January 7, 2002, which is
120 calendar days prior to the anniversary of the mailing date of this proxy
statement, and must be in compliance with applicable laws and regulations in
order to be considered for possible inclusion in the proxy statement and form of
proxy for that meeting. Under the Company's bylaws, a stockholder's notice of
business to be brought before an annual meeting must set forth, as to each
proposed matter: a) a brief description of the business and reason for
conducting such business at the meeting; b) the name and address as they appear
on the Company's books of the stockholder; c) the class and number of shares of
the Company owned by the stockholder; d) any material interest of the
stockholder in such business; and e) any other information that may be required
under Regulation 14A of the SEC rules.

     SEC rules also establish a different deadline for submission of stockholder
proposals that are not intended to be included in the Company's proxy statement
with respect to discretionary voting. The discretionary vote deadline for the
year 2002 annual meeting is March 31, 2002, 45 calendar days prior to the
anniversary of the mailing date of this proxy statement. If a stockholder gives
notice of such a proposal after the discretionary vote deadline, the Company's
proxy holders will be allowed to use their discretionary voting authority to
vote against the stockholder proposal when and if the proposal is raised at the
Company's year 2002 annual meeting.

     The Company has not been notified by any stockholder of his or her intent
to present a stockholder proposal from the floor at this year's annual meeting.

                                 PROPOSAL ONE:

                             ELECTION OF DIRECTORS

NOMINEES

     The Company has authorized a Board of six directors, and six directors are
to be elected at the Annual Meeting. Each of the directors elected at the Annual
Meeting will hold office until the Annual Meeting of Stockholders in 2002 or
until his successor has been duly elected and qualified.

     Unless otherwise instructed, the proxy holders will vote the proxies
received by them for the Company's six nominees named below, all of whom are
currently directors of the Company. In the event that any nominee of the Company
becomes unable or declines to serve as a director at the time of the Annual
Meeting, the proxy holders will vote the proxies for any substitute nominee who
is designated by the current Board of Directors to fill the vacancy. It is not
expected that any nominee listed below will be unable or will decline to serve
as a director.

meeting attended. The 1995 Director Option Plan provides for the grant of
nonstatutory stock options to certain non-employee directors of the Company who
are not representatives or beneficial owners of certain previously affiliated
investment funds, by means of an automatic, non-discretionary grant mechanism.
Each eligible outside director is granted an option to purchase 4,000 shares of

he shall have served on the Board for at least six months.

VOTE REQUIRED AND RECOMMENDATION

     The six nominees receiving the highest number of affirmative votes of the
shares entitled to vote on this matter shall be elected as directors. Votes
withheld from any director will be counted for purposes of determining the
presence or absence of a quorum but are not counted as affirmative votes. A
broker non-vote will be counted for purposes of determining the presence or
absence of a quorum, but, under Delaware law, it will have no other legal effect
upon the election of directors.

     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS VOTING "FOR" THE NOMINEES SET
FORTH ABOVE.

                                 PROPOSAL TWO:

                          AMENDMENT OF 1995 STOCK PLAN

     At the Annual Meeting, the stockholders are being asked to approve an
amendment of the Company's 1995 Stock Plan (the "Option Plan") to increase the
number of shares of Common Stock reserved for issuance thereunder by 1,400,000
shares to a total of 5,800,000 shares. The adoption of the Plan was approved

                                        4
   7

by the Board of Directors in March 1995 and became effective upon the Company's
initial public offering in May 1995. As of April 20, 2001, options to purchase
an aggregate of 2,885,483 shares of the Company's Common Stock were outstanding
under the Option Plan, with a weighted average exercise price of $15.61 per
share, and 1,112,296 shares have been issued upon exercise of stock options
granted under the Option Plan. Accordingly, as of April 20, 2001, only 402,221
shares were available for future grant under the Option Plan (excluding the
1,400,000 shares subject to approval at the Annual Meeting). In addition,
options to purchase a total of 5,562,787 shares were outstanding as follows:

                                                              5,562,787


     The 1997 NSO Plan was established in connection with the Company's
acquisition of New Media Communication Ltd. in January 1998. The 1993 Plan, 1994
Plan and the SSOP Plan were assumed in connection with the Company's acquisition
of the DiviCom business of C-Cube Microsystems Inc. in May 2000. No further
shares are available for grant under any of the above plans, except for 719,004
shares available for future grant under the 1999 NSO Plan.

     The Option Plan authorizes the Board of Directors to grant stock options to
eligible employees and consultants of the Company. The Option Plan is structured
to allow the Board of Directors to create equity incentives in order to assist
the Company in attracting, retaining and motivating the best available personnel
for the successful conduct and growth of the Company's business. The Committee
believes that the Option Plan is an essential tool to link the long-term
interests of stockholders and employees and serves to motivate executives to
make decisions that will, in the long run, give the best returns to
stockholders. The Company has, therefore, consistently included equity
incentives as a significant component of compensation for a broad range of the
Company's employees. In addition, the Company believes this practice is critical
to the Company's ability to attract and retain employees in a highly competitive
market for managerial and technical talent. The Company's geographic location in
Silicon Valley exposes it to particularly intense competition in the labor
market from both private and public companies. Equity incentives are offered by
most companies with which the Company competes for employees and it is essential
for the Company to be able to provide stock options to both new and existing
employees.

     On April 24, 2001, the Board of Directors approved an amendment to the
Option Plan to increase the number of shares reserved for issuance thereunder by
1,400,000 shares to a total of 5,800,000 shares. The stockholders are being
asked to approve this amendment at the Annual Meeting. In addition, on April 24,
2001 the Board of Directors approved an amendment to the Option Plan to prohibit
any option from being repriced, replaced or regranted through cancellation or
modification (without prior stockholder approval) if the effect would be to
reduce the exercise price of such option and the reduction in exercise price
would result in variable award accounting under Financial Accounting Standards
Board Interpretation No. 44.

     The Board of Directors believe that the remaining shares available for
grant under the Option Plan are insufficient to accomplish the purposes of the
Option Plan described above.

SUMMARY OF THE PLAN

     General. The Option Plan authorizes the Board of Directors (the "Board"),
or one or more committees which the Board may appoint from among its members
(the "Committee"), to grant options and rights to purchase Common Stock. Options
granted under the Option Plan may be either "incentive stock options" as defined
in Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), or
nonstatutory stock options, as determined by the Board or the Committee.

                                        5
   8

     Administration. The Option Plan may be administered by the Board or the
Committee. Subject to the other provisions of the Option Plan, the Board has the
authority to: (i) interpret the plan and apply its provisions; (ii) prescribe,
amend or rescind rules and regulations relating to the Option Plan; (iii) select
the persons to whom options and rights are to be granted; (iv) determine the
number of shares to be made subject to each option and right; (v) determine
whether and to what extent options and rights are to be granted; (vi) prescribe
the terms and conditions of each option and right (including the exercise price,
whether an option will be classified as an incentive stock option or a
nonstatutory option and the provisions of the stock option or stock purchase
agreement to be entered into between the Company and the grantee); (vii) amend
any outstanding option or right subject to applicable legal restrictions; except
for the reduction of the exercise price of an option in the event that the
market price of the stock shall have declined since the option was granted;
(viii) authorize any person to execute, on behalf of the Company, any instrument
required to effect the grant of an option or right; and (ix) subject to certain
limitations, take any other actions deemed necessary or advisable for the
administration of the Option Plan. All decisions, interpretations and other
actions of the Committee shall be final and binding on all holders of options or
rights and on all persons deriving their rights therefrom.

     Eligibility. The Option Plan provides that options and rights may be
granted to the Company's employees and independent consultants. Incentive stock
options may be granted only to employees. Any optionee who owns more than 10% of
the combined voting power of all classes of outstanding stock of the Company (a
"10% Stockholder") is not eligible for the grant of an incentive stock option
unless the exercise price of the option is at least 110% of the fair market
value of the Common Stock on the date of grant.

     Limitations. Section 162(m) of the Code places limits on the deductibility
for federal income tax purposes of compensation paid to certain executive
officers of the Company. In order to preserve the Company's ability to deduct
the compensation income associated with options and stock purchase rights
granted to such persons, the Plan provides that no employee may be granted, in
any fiscal year of the Company, options and stock purchase rights to purchase
more than 600,000 shares of Common Stock.

     Terms and Conditions of Options. Each option granted under the Option Plan
is evidenced by a written stock option agreement between the optionee and the
Company and is subject to the following terms and conditions:

          (a) Exercise Price. The Board or the Committee determines the exercise
     price of options at the time the options are granted. However, excluding
     options issued to 10% Stockholders, the exercise price of an incentive
     stock option must not be less than 100% of the fair market value of the
     Common Stock on the date the option is granted, and the exercise price
     under a nonstatutory option shall be determined by the administrator of the
     Option Plan, but may not be less than 85% of the fair market value of the
     Common Stock on the date the option is granted. As the Company's Common
     Stock is listed on the Nasdaq National Market, the fair market value is the
     closing sale price for the Common Stock (or the closing bid if no sales
     were reported) on the date the option is granted. In addition, no option
     granted under the Option Plan may be repriced, replaced or regranted
     through cancellation or modification (without stockholder approval) if the
     effect would be to reduce the exercise price of such option and the
     reduction in exercise price would result in variable award accounting under
     Financial Accounting Standards Board Interpretation No. 44.

          (b) Form of Consideration. The means of payment for shares issued upon
     exercise of an option is specified in each option agreement and generally
     may be made by cash, check, a full-recourse promissory note, other shares
     of Common Stock of the Company owned by the optionee, delivery of an
     exercise notice together with irrevocable instructions to a broker to
     deliver the exercise price to the Company from sale or loan proceeds, or by
     a combination thereof.

          (c) Exercise of the Option. Each stock option agreement will specify
     the term of the option and the date when the option is to become
     exercisable. However, in no event shall an option granted under the Option
     Plan be exercised more than 10 years after the date of grant.

                                        6
   9

          Moreover, in the case of an incentive stock option granted to a 10%
     Stockholder, the term of the option shall be for no more than five years
     from the date of grant. To date, all options granted under the Option Plan
     have vested 25% on the first anniversary from the date of grant and 1/48
     per month thereafter.

          (d) Termination of Employment. If an optionee's employment terminates
     for any reason (other than death or permanent disability), then all options
     held by such optionee under the Option Plan expire upon the earlier of (i)
     such period of time as is set forth in his or her option agreement (but not
     to exceed three months after the termination of his or her employment in
     the event of an incentive stock option) or (ii) the expiration date of the
     option. The optionee may exercise all or part of his or her option at any
     time before such expiration to the extent that such option was exercisable
     at the time of termination of employment.

          (e) Permanent Disability. If an employee is unable to continue
     employment with the Company as a result of permanent and total disability
     (as defined in the Code), then all options held by such optionee under the
     Option Plan shall expire upon the earlier of (i) 12 months after the date
     of termination of the optionee's employment or (ii) the expiration date of
     the option. The optionee may exercise all or part of his or her option at
     any time before such expiration to the extent that such option was
     exercisable at the time of termination of employment.

          (f) Death. If an optionee dies while employed by the Company, his or
     her option shall expire upon the earlier of (i) 12 months after the
     optionee's death or (ii) the expiration date of the option. The executors
     or other legal representative or the optionee may exercise all or part of
     the optionee's option at any time before such expiration to the extent that
     such option was exercisable at the time of death.

          (g) Termination of Options. Each stock option agreement will specify
     the term of the option and the date when all or any installment of the
     option is to become exercisable. Notwithstanding the foregoing, however,
     the term of any incentive stock option shall not exceed 10 years from the
     date of grant. No options may be exercised by any person after the
     expiration of its term.

          (h) Nontransferability of Options. During an optionee's lifetime, his
     or her option(s) shall be exercisable only by the optionee and shall not be
     transferable other than by will or laws of descent and distribution.

          (i) Limitations. If the aggregate fair market value of all shares of
     Common Stock subject to an optionee's incentive stock option which are
     exercisable for the first time during any calendar year exceeds $100,000,
     the excess options shall be treated as nonstatutory options.

          (j) Other Provisions. The stock option agreement may contain such
     terms, provisions and conditions that are inconsistent with the Option Plan
     as may be determined by the Board or the Committee.

     Stock Purchase Rights. The Option Plan permits the Company to grant rights
to purchase Common Stock either alone or in tandem with other awards granted
under the Option Plan and/or cash awards made outside of the Option Plan. Rights
may be granted to purchase up to an aggregate of 586,498 shares of Common Stock
(which is equal to the sum of the 446,498 shares available for future grant as
Stock Purchase Rights as of the Record Date plus 140,000 shares or 10% of the
1,400,000 share increase which is the subject of this Proposal Two). The offer
of a right must be accepted within six months of its grant by the execution of a
restricted stock purchase agreement between the Company and the offeree and the
payment of the purchase price of the shares. Unless the Board or the Committee
determines otherwise, the restricted stock purchase agreement shall grant the
Company a repurchase option exercisable upon termination of the purchaser's
employment or consulting relationship with the Company. The purchase price for
any shares repurchased by the Company shall be the original price paid by the
purchaser. The repurchase option shall lapse at such rate as the Board or the
Committee may determine.

     Adjustment Upon Changes in Capitalization, Corporate Transactions. In the
event that the stock of the Company is changed by reason of any stock split,
reverse stock split, stock dividend, recapitalization or other change in the
capital structure of the Company, appropriate proportional adjustments shall be
made in the number and class of shares of stock subject to the Option Plan, the
number and class of shares of stock subject

                                        7
   10

to any option or right outstanding under the Option Plan, and the exercise price
of any such outstanding option or right. Any such adjustment shall be made upon
approval of the Board and, if required, the stockholders of the Company, whose
determination shall be conclusive. Notwithstanding the above, in connection with
any merger, consolidation, acquisition of assets or like occurrence involving
the Company, each outstanding option and right may be assumed or an equivalent
option or right may be substituted by a successor corporation. The Administrator
may, in lieu of such assumption or substitution, provide (i) for the Optionee to
have the right to exercise the Option or Stock Purchase Right as to all or a
portion of the Optioned Stock, including Shares as to which it would not
otherwise be exercisable, and (ii) for any Restricted Stock held by an Optionee
to become fully vested.

     Amendment, Suspensions and Termination of the Plan. The Board may amend,
suspend or terminate the Option Plan at any time; provided, however, that
stockholder approval is required for any amendment to the extent necessary to
comply with Rule 16b-3 promulgated under the Securities Exchange Act of 1934
("Rule 16b-3") or Section 422 of the Code, or any similar rule or statute. In
any event, the Option Plan will terminate automatically in 2005.

     Federal Tax Information. Options granted under the Option Plan may be
either "incentive stock options," as defined in Section 422 of the Code, or
nonstatutory options.

     An optionee who is granted an incentive stock option will not recognize
taxable income either at the time the option is granted or upon its exercise,
although the exercise may subject the optionee to alternative minimum tax. Upon
the sale or exchange of the shares more than two years after grant of the option
and one year after exercising the option, any gain or loss will be treated as
long-term capital gain or loss. If these holding periods are not satisfied, the
optionee will recognize ordinary income at the time of sale or exchange equal to
the difference between the exercise price and the lower of (i) the fair market
value of the shares at the date of the option exercise or (ii) the sale price of
the shares. A different rule for measuring ordinary income upon such a premature
disposition may apply if the optionee is also an officer, director, or 10%
stockholder of the Company. The Company will be entitled to a deduction in the
same amount as the ordinary income recognized by the optionee. Any gain or loss
recognized on such a premature disposition of the shares in excess of the amount
treated as ordinary income will be characterized as long-term or short-term
capital gain or loss, depending on the holding period.

     All other options which do not qualify as incentive stock options are
referred to as nonstatutory options. An optionee will not recognize any taxable
income at the time he is granted a nonstatutory option. However, upon its
exercise, the optionee will recognize taxable income generally measured as the
excess of the then fair market value of the shares purchased over the purchase
price. Any taxable income recognized in connection with an option exercise by an
optionee who is also an employee of the Company will be subject to tax
withholding by the Company. Upon resale of such shares by the optionee, any
difference between the sale price and the optionee's purchase price, to the
extent not recognized as taxable income as described above, will be treated as
long-term or short-term capital gain or loss, depending on the holding period.

     Unless limited by Section 162(m) of the Code, the Company will be entitled
to a tax deduction in the same amount as the ordinary income recognized by the
optionee with respect to shares acquired upon exercise of a nonstatutory option.

     A recipient of restricted stock will have ordinary income equal to the fair
market value of the shares at the time if and when the share restrictions lapse.
Under current federal tax law, however, the employee may elect to include as
ordinary income for the year of the award the fair market value of the shares on
the grant date. The restrictions on the shares will not affect fair market value
for purposes of such an election. If the election is made, the recipient will
not incur additional tax liability until the sale or disposition of the shares.
Unless limited by Section 162(m) of the Code, the Company is entitled to a
federal tax deduction in the same amount and at the same time as the employee
realizes ordinary income.

     The foregoing is only a summary of the effect of federal income taxation
upon the optionee and the Company with respect to the grant and exercise of
options under the Option Plan, does not purport to be

                                        8

complete, and does not discuss the tax consequences of the optionee's death or
the income tax laws of any municipality, state or foreign country in which an
optionee may reside.

(1) The options were granted pursuant to the Company's 1995 Stock Plan, and
    become exercisable at a rate of 1/4 of the shares subject to the option one
    year after the date of grant and an additional 1/48 of the shares at the end
    of each month thereafter, subject to continued service as an employee. The
    term of each option is ten years.

(2) Potential gains are net of the exercise price but before taxes associated
    with the exercise. The 5% and 10% assumed annual rates of compounded stock
    appreciation are mandated by the rules of the Securities and Exchange
    Commission and do not represent the Company's estimate or projection of the
    future Common Stock price. Actual gains, if any, on stock option exercises
    will depend on the future financial performance of the Company, overall
    market conditions and the option holders' continued employment through the
    vesting period.

     The following table provides information with respect to the exercise of
stock options during 2000 and the value of stock options held as of December 31,

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Compensation Committee of the Board of Directors currently consists of
Messrs. Kvamme and Lemieux. No member of the Compensation Committee or executive
officer of the Company has a relationship that would constitute an interlocking
relationship with executive officers or directors of another entity.

REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE
COMPENSATION

     The members of the Compensation Committee of the Board of Directors are
Messrs. Kvamme and Lemieux, neither of whom is an employee of the Company.

     The Compensation Committee is responsible for the approval of the Company's
executive compensation policies. The Committee reviews and approves the base
salary and incentive compensation paid to executive

                                        11
   14

officers and administers the Company's stock plans. The Company's Board of
Directors reviews and approves all stock option grants.

  Compensation Philosophy

     The Company's executive compensation programs are designed to attract,
motivate and retain executives who will contribute significantly to the
long-term success of the Company and the enhancement of stockholder value. In
addition to base salary, certain elements of total compensation are payable in
the form of variable incentive plans tied to the performance of the Company and
the individual, and in equity-based plans designed to closely align executive
and stockholder interests.

     The three key components of executive compensation in 2000 were:

     - Base Salary

     - Incentive Bonus Plan

     - Stock Option Plan

  Base Salary

     Base salary for executives, including that of the chief executive officer,
is set according to the responsibilities of the position, the specific skills
and experience of the individual and the competitive market for executive
talent. In order to evaluate the competitive position of the Company's salary
structure, the Committee makes reference to compensation surveys of comparable
companies in the high-technology sector, the Company's industry and the
Company's geographic location. Executive salary levels are set to approximate
average rates, with the intent that superior performance under incentive bonus
plans will enable the executive to elevate his total cash compensation to levels
that are above the average of comparable companies. The Committee reviews
salaries annually and adjusts them as appropriate to reflect changes in market
conditions and individual performance and responsibilities.

  Incentive Bonus Plan

     The Company's annual incentive bonus plan reflects the Committee's belief
that a meaningful component of executive compensation should be contingent on
the performance of the Company and the individual executive officer. In 2000,
the Company's incentive bonus plan was based in part upon the attainment of
certain revenue and operating profit goals with a target bonus established for
each participant. The Committee also has discretion to adjust a portion of the
actual bonus according to the Committee's evaluation of each individual's
performance. In 2000, the Company's financial results did not meet internal or
external expectations of either revenue or pro forma operating income and no
bonuses were paid based on financial performance. The Committee exercised its
discretion to pay bonuses according to its evaluation of the individual
performance of each executive officer.

  Stock Option Plans

     The Committee believes that the Company's stock option plans are an
essential tool to link the long-term interests of stockholders and employees,
especially executive management, and serves to motivate executives to make
decisions that will, in the long run, give the best returns to stockholders.
Stock options are generally granted when an executive joins the Company, and on
an annual basis thereafter. These options typically vest over a four year period
and are granted at an exercise price equal to the fair market value of the
Company's Common Stock at the date of grant. The size of initial option grants
is based upon the position, responsibilities and expected contribution of the
individual, with subsequent grants also taking into account the individual's
performance and the vesting status of previously granted options. This approach
is designed to maximize stockholder value over a long term, as no benefit is
realized from the option grant unless the price of the Company's Common Stock
has increased over a number of years.

                                        12
   15

     In addition to the Option Plan, executive officers are eligible to
participate in the Company's 1995 Employee Stock Plan. This Plan allows eligible
employees to purchase the Company's Common Stock at a price equal to 85% of the
lower of the fair market value at the beginning of the offering period or the
fair market value at the end of the purchase period, with the amount of discount
limited to 10% of base salary.

     Other elements of executive compensation include life and long-term
disability insurance, medical benefits and a 401(k) deferred compensation plan.
The Company makes matching contributions to the 401(k) plan up to $750 per annum
per participant. All such benefits are available to all regular, full-time U.S.
employees of the Company.

     The compensation of the Chief Executive Officer in 2000 was determined in a
manner substantially consistent with that of other executive officers.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

     The Audit Committee of the Board of Directors of Harmonic serves as the
representative of the Board for general oversight of Harmonic's financial
accounting and reporting process, system of internal control, audit process, and
process for monitoring the compliance with laws and regulations. Harmonic's
management has primary responsibility for preparing financial statements and the
financial reporting process.

     The Audit Committee is composed of four non-employee members, each of whom
is independent as defined by the Nasdaq rules. Harmonic's independent
accountants, PricewaterhouseCoopers LLP, are responsible for expressing an
opinion on the conformity of Harmonic's audited financial statements to

                                        14
   17

generally accepted accounting principles. A copy of the Audit Committee Charter,
which was first adopted by the Board of Directors on July 18, 2000 is attached
to this Proxy Statement.

     The Audit Committee of the Board of Directors has:

     - reviewed and discussed the audited financial statements with Company
       management;

     - discussed with PricewaterhouseCoopers LLP the matters required to be
       discussed by Statement of Accounting Standards 61; and

     - reviewed the written disclosures and the letter from
       PricewaterhouseCoopers LLP required by Independence Standards Board
       Standard No. 1 and has discussed with PricewaterhouseCoopers LLP its
       independence.

     Based on the foregoing review and discussions, the Audit Committee
recommended to the Board of Directors that the audited financial statements be
included in Harmonic's 2000 Annual Report on Form 10-K filed with the Securities
& Exchange Commission.

     Fees Billed to the Company by PricewaterhouseCoopers LLP during Fiscal 2000

     Audit Fees: The aggregate fees billed by PricewaterhouseCoopers for
professional services rendered for the audit of Harmonic's fiscal year 2000
financial statements, and for the reviews of the financial statements included
in each of the Company's Forms 10-Q are $300,000.

     Financial Information Systems Design and Implementation
Fees: PricewaterhouseCoopers did not bill for any professional services for
financial information systems design or implementation for fiscal year 2000.

     All Other Fees: Aggregate fees billed for all other services rendered by
PricewaterhouseCoopers, principally accounting and tax services related to
acquisitions and registration statements, for fiscal year 2000 are $513,000.

     The Audit Committee has considered whether the services provided by
PricewaterhouseCoopers LLP are compatible with maintaining the independence of
PricewaterhouseCoopers LLP and has concluded that the independence of
PricewaterhouseCoopers LLP is maintained and is not compromised by the services
provided.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act") requires the Company's executive officers and directors and
persons who own more than ten percent of a registered class of the Company's
equity securities to file an initial report of ownership on Form 3 and changes
in ownership on Form 4 or Form 5 with the Securities and Exchange Commission
(the "SEC") and the National Association of Securities Dealers, Inc. Executive
officers, directors and greater than ten percent stockholders are also required
by SEC rules to furnish the Company with copies of all Section 16(a) forms they
file. Based solely on its review of the copies of such forms received by it or
written representations from certain reporting persons, the Company believes
that, with respect to 2000, all filing requirements applicable to its officers,
directors and ten percent stockholders were complied with.

                                 OTHER MATTERS
