NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) which Harmonic Inc. (the “Company”) considers necessary for a fair presentation of the results of operations for the unaudited interim periods covered and the consolidated financial condition of the Company at the date of the balance sheets. The quarterly financial information is unaudited. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K, which was filed with the Securities and Exchange Commission on March 9, 2004. The interim results presented herein are not necessarily indicative of the results of operations that may be expected for the full fiscal year ending December 31, 2004, or any other future period. The Company’s fiscal quarters end on the Friday nearest the calendar quarter end, except for the fourth quarter which ends on December 31.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Employee Stock Plans

Harmonic accounts for employee stock option plans in accordance with Accounting Principles Board No. 25 (“APB 25”), “Accounting for Stock Issued to Employees,” and has adopted the disclosure requirements under SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure.” If charges for Harmonic’s stock plans had been determined based on the fair value method at the grant dates, as prescribed in SFAS No. 123, “Accounting for Stock-Based Compensation”, the Company’s net loss and net loss per share would have been as follows:

These pro forma amounts may not be representative of the effects for future years as options vest over several years and additional awards are generally made each year.

In accordance with SFAS No. 123, stock options granted to non-employees are valued using the Black-Scholes option-pricing model and stock expense is recognized as earned. Stock expense is recognized on an accelerated basis using the multiple option method presented in Financial Accounting Standards Board Interpretation No. 28 (“FIN 28”), “Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans”. For the three month period ended April 2, 2004, Harmonic recorded $8 thousand of non-employee stock expenses. For the three month period ended March 28, 2003, Harmonic recorded $17 thousand of non-employee stock expenses.

NOTE 3 — CASH, CASH EQUIVALENTS AND INVESTMENTS

Cash equivalents are comprised of highly liquid investment-grade investments with original maturities of three months or less at the date of purchase. Harmonic’s short-term investments are stated at fair value, which

6

approximate the cost of investments and are principally comprised of government and corporate debt securities. The Company classifies its investments as available for sale in accordance with SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities,” and states its investments at estimated fair value, with unrealized gains and losses reported in other comprehensive income. The specific identification method is used to determine the cost of securities disposed of, with realized gains and losses reflected in other income and expense. Investments are anticipated to be used for current operations and are therefore classified as current assets, even though maturities may extend beyond one year. At April 2, 2004 and December 31, 2003, cash, cash equivalents and short-term investments are summarized as follows:

Harmonic’s short-term investments are stated at fair value, which approximates the cost of investments and are comprised of principally government and corporate debt securities.

NOTE 4 — INVENTORIES

Inventories consist of:

NOTE 5 — GOODWILL AND IDENTIFIED INTANGIBLES

Harmonic accounts for goodwill and other intangibles in accordance with SFAS No. 142, “Goodwill and Other Intangible Assets”, which requires, among other things, that goodwill and intangible assets with indefinite useful lives no longer be amortized and the testing of existing goodwill and other intangibles for impairment at least annually. Management believes that the operating segments, Convergent Systems, or CS, for digital headend systems, and Broadband Access Networks, or BAN, for fiber optic systems, represent the Company’s reporting units, and CS is the only reporting unit with goodwill and intangible assets. For the three months ended April 2, 2004 and March 28, 2003, the Company recorded a total of $3.5 million of amortization expense in each period for identified intangibles of which $1.5 million was included in cost of sales in each period. Estimated future amortization expense of identified intangibles is $10.4 million for the remaining nine months of 2004, and $4.6 million for the fiscal year 2005. Future amortization expense to be included in cost of sales is estimated to be $4.6 million for the remainder of 2004, and $2.1 million for the fiscal year 2005.

The following is a summary of goodwill and intangible assets as of April 2, 2004 and December 31, 2003:

NOTE 6 — CREDIT FACILITIES AND LONG-TERM DEBT

Harmonic has a bank line of credit facility with Silicon Valley Bank, which provides for borrowings up to $13.5 million, including $3.5 million for equipment under a secured term loan. This facility, which was amended and restated in December 2003 and expires in December 2004, contains financial and other covenants, including the requirement for Harmonic to maintain cash, cash equivalents and short-term investments, net of credit extensions, of not less than $65.0 million. If Harmonic is unable to maintain this cash, cash equivalents and short-term investments balance or satisfy the additional affirmative covenant requirements, Harmonic would be in noncompliance with the facility. In the event of noncompliance by Harmonic with the covenants under the facility, Silicon Valley Bank would be entitled to exercise its remedies under the facility which include declaring all obligations immediately due and payable and disposing of the collateral if obligations were not repaid. At April 2, 2004, Harmonic was in compliance with the covenants under this line of credit facility. Future borrowings pursuant to the line bear interest at the bank’s prime rate or prime rate plus 1.0% (prime rate plus 0.5%-1.5% for equipment borrowings) depending upon the Company’s total cash position and previous six months’ revenue. Borrowings are payable monthly and are collateralized by all of Harmonic’s assets. As of April 2, 2004, $1.5 million was outstanding under the equipment term loan portion of this facility, of which $0.2 million was borrowed during 2004. The term loan is payable monthly, including principal and interest at 4.5% per annum on outstanding borrowings as of April 2, 2004 and matures at various dates through March 2007. Other than standby letters of credit and guarantees (Note 12), there were no other outstanding borrowings or commitments under the line of credit facility as of April 2, 2004.

NOTE 7 — NET LOSS PER SHARE

The basic net loss per share is computed by dividing the net loss attributable to common stockholders for the period by the weighted average number of common shares outstanding during the period. The diluted net loss per share is the same as the basic net loss per share for the three month periods ended April 2, 2004 and March 28, 2003 because common shares issuable upon the exercise of stock options are only considered when their effect would be dilutive. During the three month periods ended April 2, 2004 and March 28, 2003, 5.6 million and 6.9 million, respectively, of weighted average antidilutive options were excluded from the net loss per share computations because their effect was antidilutive.

NOTE 8 — COMPREHENSIVE LOSS

The Company’s total comprehensive loss was as follows:

NOTE 9 — RESTRUCTURING AND EXCESS FACILITIES

As a result of uncertain market conditions and lower sales during the second half of 2002, the Company implemented workforce reductions of approximately 120 full-time employees and changed its estimates related to accrued excess facilities with regard to the expected timing and amount of sublease income due to the substantial surplus of vacant commercial space in the San Francisco Bay Area. In connection with these actions, Harmonic recorded $1.5 million and paid $1.1 million for severance and other costs and recorded an additional excess facilities charge of $22.5 million, net of sublease income, to selling, general and administrative expenses during the second half of 2002.

During the three months ended April 2, 2004, Harmonic paid $34 thousand of severance and other costs, and no liability remains. As of April 2, 2004, accrued excess facilities cost totaled $33.5 million of which $5.9 million was included in current accrued liabilities and $27.6 million in other non-current liabilities. The Company incurred cash outlays of $1.2 million during the first three months of 2004, principally for lease payments, property taxes, insurance and other maintenance fees related to vacated facilities. Harmonic expects to pay approximately $4.9 million of excess facilities lease costs, net of estimated sublease income, for the remainder of 2004 and to pay the remaining $28.6 million, net of estimated sublease income, over the remaining lease terms through September 2010. Harmonic reassesses this liability quarterly and adjusts as necessary based on changes in the timing and amounts of expected sublease rental income or changes in other assumptions due to changes in market conditions. In the event the Company is unable to achieve expected levels of sublease rental income, Harmonic will need to revise its estimate of the liability, which could materially impact the Company’s financial position, liquidity, cash flows or results of operations.

The following table summarizes restructuring activities:

NOTE 10 — SEGMENT REPORTING

Operating segments are defined as components of an enterprise that engage in business activities for which separate financial information is available and evaluated by the chief operating decision maker. Harmonic is organized as two operating segments, Convergent Systems, or CS, for digital headend systems, and Broadband Access Networks, or BAN, for fiber optic systems. Each segment has its own management team directing its product development, marketing strategies and its customer service requirements. A separate sales force generally supports both divisions with appropriate product and market specialization as required.

The results of the reportable segments are derived directly from Harmonic’s management reporting system. These results reported below are based on Harmonic’s method of internal reporting and are not necessarily presented in conformity with generally accepted accounting principles. Management measures performance of each segment based on several metrics, including revenue, and income or loss from segment operations. These results are used, in

9

part, to evaluate the performance of, and allocate resources to each of the segments. Income (loss) from segment operations excludes intangible amortization expense, corporate expenses, eliminations, and interest and other income. Corporate expenses and eliminations include human resources, legal, finance and other corporate departments and intercompany eliminations. Net income or loss, and assets and liabilities are not internally reported by business segment.

NOTE 11 — RELATED PARTY

A director of Harmonic is also a director of Terayon Communications, with whom the Company has a reseller agreement for certain products. Product purchases from Terayon were approximately $1.0 million and $0.3 million for the three month periods ended April 2, 2004 and March 28, 2003, respectively. As of April 2, 2004 and December 31, 2003, Harmonic had liabilities to Terayon of $0.2 million and $0.3 million, respectively, for inventory purchases.

NOTE 12 — GUARANTEES AND INDEMNIFICATIONS

Warranties. The Company accrues for estimated warranty costs at the time of product shipment. Management periodically reviews the estimated fair value of its warranty liability and adjusts based on the terms of warranties provided to customers, historical and anticipated warranty claims experience, and estimates of the timing and cost of specified warranty claims. Activity for the Company’s warranty accrual, which is included in accrued liabilities, is summarized below:

		Three Months Ended
In Thousands (Unaudited)		April 2, 2004				March 28, 2003
Balance at the beginning of the period		$	4,886			$	5,866
Accrual for warranties			1,254				837
Warranty costs incurred			(1,352	)			(1,539	)
Balance at the end of the period		$	4,788			$	5,164

Standby Letters of Credit. As of April 2, 2004 the Company’s financial guarantees consisted of standby letters of credit outstanding, which were related principally to a litigation settlement, customs bond requirements and corporate purchase cards. The maximum amount of potential future payments under these arrangements was $2.8 million.

10

Guarantees. As of April 2, 2004, Harmonic had no outstanding guarantees.

Indemnifications. Harmonic indemnifies the members of its Board of Directors and its officers pursuant to the requirements of its bylaws and pursuant to indemnification agreements entered into with such persons, and some of its suppliers and customers for specified intellectual property rights pursuant to certain parameters and restrictions. The scope of these indemnities varies, but in some instances, includes indemnification for damages and expenses (including reasonable attorneys’ fees). No amounts have been accrued in respect of the indemnifications provisions at April 2, 2004.

NOTE 13 — LEGAL PROCEEDINGS

Between June 28 and August 25, 2000, several actions alleging violations of the federal securities laws by Harmonic and certain of its officers and directors (some of whom are no longer with Harmonic) were filed in or removed to the United States District Court for the Northern District of California. The actions subsequently were consolidated.

A consolidated complaint, filed on December 7, 2000, was brought on behalf of a purported class of persons who purchased Harmonic’s publicly traded securities between January 19 and June 26, 2000. The complaint also alleged claims on behalf of a purported subclass of persons who purchased C-Cube securities between January 19 and May 3, 2000. In addition to Harmonic and certain of its officers and directors, the complaint also named C-Cube Microsystems Inc. and several of its officers and directors as defendants. The complaint alleged that, by making false or misleading statements regarding Harmonic’s prospects and customers and its acquisition of C-Cube, certain defendants violated sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The complaint also alleged that certain defendants violated section 14(a) of the Exchange Act and sections 11, 12(a)(2), and 15 of the Securities Act of 1933 by filing a false or misleading registration statement, prospectus, and joint proxy in connection with the C-Cube acquisition.

On July 3, 2001, the Court dismissed the consolidated complaint with leave to amend. An amended complaint alleging the same claims against the same defendants was filed on August 13, 2001. Defendants moved to dismiss the amended complaint on September 24, 2001. On November 13, 2002, the Court issued an opinion granting the motions to dismiss the amended complaint without leave to amend. Judgment for defendants was entered on December 2, 2002. On December 12, 2002, plaintiffs filed a motion to amend the judgment and for leave to file an amended complaint pursuant to Rules 59(e) and 15(a) of the Federal Rules of Civil Procedure. On June 6, 2003, the Court denied plaintiffs’ motion to amend the judgment and for leave to file an amended complaint. Plaintiffs filed a notice of appeal on July 1, 2003. Plaintiffs filed their opening brief on December 3, 2003. Defendants filed their answering briefs on March 2, 2004. Plaintiffs’ reply brief was filed on April 16, 2004. No hearing has been scheduled yet.

A derivative action purporting to be on behalf of Harmonic was filed against its then-current directors in the Superior Court for the County of Santa Clara on September 5, 2000. Harmonic also was named as a nominal defendant. The complaint is based on allegations similar to those found in the securities class action and claims that the defendants breached their fiduciary duties by, among other things, causing Harmonic to violate federal securities laws. The derivative action was removed to the United States District Court for the Northern District of California on September 20, 2000. All deadlines in this action were stayed pending resolution of the motions to dismiss the securities class action. On July 29, 2003, the Court approved the parties’ stipulation to dismiss this derivative action without prejudice and to toll the applicable limitations period. The limitations period is tolled until fourteen days after (1) defendants provide plaintiff with a copy of the mandate issued by the Ninth Court in the securities action or (2) either party provides written notice of termination of the tolling period, whichever is first.

A second derivative action purporting to be on behalf of Harmonic was filed in the Superior Court for the County of Santa Clara on May 15, 2003. It alleges facts similar to those previously alleged in the securities class action and the federal derivative action. The complaint names as defendants former and current Harmonic officers and directors, along with former officers and directors of C-Cube Microsystems, Inc., who were named in the securities class action. The complaint also names Harmonic as a nominal defendant. The complaint alleges claims for abuse of control, gross mismanagement, and waste of corporate assets against the Harmonic defendants, and claims for breach of fiduciary duty, unjust enrichment, and negligent misrepresentation against all defendants. On July 22, 2003, the Court approved the parties’ stipulation to stay the case pending resolution of the appeal in the securities

11

class action. Although the parties initially agreed in principle to a dismissal without prejudice on similar terms as in the federal derivative action, after further discussion, the parties decided that the stay currently in place suffices to protect their respective interests.

Based on its review of the complaints filed in the securities class action, Harmonic believes that it has meritorious defenses and intends to defend itself vigorously. There can be no assurance, however, that Harmonic will prevail. No estimate can be made of the possible range of loss associated with the resolution of this contingency and accordingly, Harmonic has not recorded a liability. An unfavorable outcome of this litigation could have a material adverse effect on Harmonic’s business, operating results, financial position or cash flows.

On July 3, 2003, Stanford University and Litton Systems filed a complaint in U.S. District Court for the Central District of California alleging that optical fiber amplifiers incorporated into certain of Harmonic’s products infringe U.S. Patent No. 4,859,016. This patent expired in September 2003. The complaint seeks injunctive relief, royalties and damages. Harmonic has not been served in the case. Harmonic is currently evaluating its position with respect to this patent and has engaged in discussions with the plaintiff regarding potential settlement of the matter. At this time, we are unable to determine whether we will be able to settle this litigation on reasonable terms or at all, nor can we predict the impact of an adverse outcome of this litigation if we elect to defend against it. No estimate can be made of the possible range of loss associated with the resolution of this contingency and accordingly, we have not recorded a liability associated with the outcome of a negotiated settlement or an unfavorable verdict in litigation. An unfavorable outcome of this matter could have a material adverse effect on Harmonic’s business, operating results, financial position or cash flows.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including statements regarding our expectations of continued customer concentration; increasing competition between cable and satellite operators to offer more channels of digital video and new services; our expectations that international sales will continue to account for a significant portion of our net sales for the foreseeable future; our expectations regarding the amount of amortization of intangible operating expense we will incur during the remainder of 2004; and our belief that our existing liquidity sources will satisfy our cash requirements for at least the next 12 months. These statements involve risks and uncertainties as well as assumptions that, if they were to never materialize or prove incorrect, could cause actual results to differ materially from those projected, expressed or implied in the forward-looking statements. These risks and uncertainties include those set forth under “Factors That May Affect Future Results of Operations” below and elsewhere in this Quarter Report on Form 10-Q and that are otherwise described from time to time in Harmonic’s filings with the Securities and Exchange Commission.

Overview

Harmonic designs, manufactures and sells digital video systems and fiber optic systems that enable network operators to provide a range of interactive and advanced digital services that include digital video, video-on-demand, or VOD, high definition (HD) television, high-speed Internet access and telephony. Historically, most of our sales have been derived from sales of digital headend products and fiber optic transmission systems to cable television and satellite operators. We offer digital headend products to enable delivery of digital video, voice and data over satellite and wireless networks and cable systems. We also derive a portion of our revenue, directly or indirectly, from sales of fiber optic transmission systems to cable television operators and from telephone companies that offer video services to their customers.

Harmonic has been organized into two operating divisions, Convergent Systems, or CS, for digital video systems, and Broadband Access Networks, or BAN, for fiber optic systems. In the first quarter of 2004, sales of CS products accounted for approximately 65% of net sales, while BAN products accounted for approximately 35% of net sales.

Historically, a majority of our net sales have been to relatively few customers, and due in part to the consolidation of ownership of cable television and direct broadcast satellite systems, we expect this customer concentration to continue for the foreseeable future. In the first quarter of 2004, sales to Comcast Cable, Echostar Satellite Corp. and Cox Communications accounted for 14%, 14% and 13% of net sales, respectively. In the first quarter of 2003, sales

12

to Comcast Cable, DIRECTV, and Echostar Satellite Corp. accounted for 21%, 18% and 14% of net sales, respectively.

Industry capital spending has been and continues to be generally weak compared to levels seen in 1999 and early 2000. However, we believe that our sequential quarterly sales increases in 2003 and the increase in net sales in the first quarter of 2004 compared to the first quarter of 2003 reflected a firmer industry capital spending environment worldwide which favorably impacted Harmonic. We believe that the improved environment was reflected by an increase of 49% in Harmonic’s net sales in the first quarter of 2004 as compared with the first quarter of 2003. We believe that this improvement in the industry capital spending environment was, in part, a result of the intensifying competition between cable and satellite operators to offer more channels of digital video and new services, such as VOD and HD television, and an overall improvement in the cable industry capital market. For example, Adelphia Communications, which had declared bankruptcy in June 2002, has obtained debtor-in-possession financing of $1.5 billion, allowing it to resume certain capital expenditure programs. Other customers, such as NTL, have already emerged from bankruptcy.

Sales to customers outside of the United States in the first quarter of 2004 represented 33% of our total net sales. A significant portion of international sales are made to distributors and system integrators, which are generally responsible for importing the products and providing installation and technical support and service to customers within their territory. We expect international sales to continue to account for a significant portion of our net sales for the foreseeable future.

Results of Operations

Harmonic’s historical consolidated statements of operations data for the first quarter of 2004 and 2003 as a percentage of net sales, are as follows:

Net Sales

Harmonic’s consolidated, segment and international net sales in the first quarter of 2004 as compared with the corresponding prior period is presented in the table below. Also presented is the related dollar and percentage increase (decrease) in consolidated, segment and international net sales in the first quarter of 2004 as compared with the first quarter of 2003 (in thousands, except percentages).

13

Segmental Sales Data:

Net sales increased in the CS division in the first quarter of 2004 compared to the first quarter of 2003, principally due to stronger spending by domestic and international customers. The CS sales in the first quarter of 2004 compared to the first quarter of 2003 benefited from significantly higher sales of the Narrowcast Services Gateway, or NSG, as a result of continued VOD deployments. The increase in the BAN division net sales in the first quarter of 2004 compared to the first quarter of 2003 was due to stronger spending in the U.S. by select cable operators and to a smaller degree by increased spending by international cable operators. BAN sales in the first quarter of 2004 compared to the first quarter of 2003 benefited from increased sales of transmitters and nodes for major network upgrades as well as continuing network improvements, such as node segmentation.

Geographic Sales Data:

Net sales in the U.S. and international markets increased in the first quarter of 2004 compared to the first quarter of 2003 in both the CS and BAN divisions. The higher CS division sales in the first quarter of 2004 compared to the first quarter of 2003 was due to stronger spending by domestic customers primarily for the roll-out of new services, such as VOD and HD television programming. The international sales increase in CS division sales in the first quarter of 2004 compared to the first quarter of 2003 reflects the stronger capital spending in most markets, and was strongest in Europe, Asia and the Caribbean. The BAN division sales increase in the first quarter of 2004 compared to the first quarter of 2003 was due to increased capital spending by select cable operators in both the domestic and international markets.

Gross Profit

Harmonic’s gross profit and gross profit as a percentage of consolidated net sales in the first quarter of 2004 as compared with the corresponding prior year period are presented in the table below. Also presented is the related dollar and percentage increase (decrease) in gross profit in the first quarter of 2004 as compared with the first quarter of 2003 (in thousands, except percentages).

14

The increase in gross profit in the first quarter of 2004 compared to the first quarter of 2003 was primarily due to higher sales, product mix and improvement in factory efficiencies. The increased gross margin percentage in the first quarter of 2004 compared to the first quarter of 2003 was primarily attributable to lower manufacturing costs due to higher sales volume and lower third party manufacturing costs. In addition, gross profit for the first quarter of 2004 included a benefit of $0.7 million related to products sold for which the cost basis had been written down in prior years, as compared to $1.1 million in the first quarter of 2003.

Research and Development

Harmonic’s research and development expense and the expense as a percentage of consolidated net sales in the first quarter of 2004 as compared with the corresponding prior year period are presented in the table below. Also presented is the related dollar and percentage increase (decrease) in research and development expense in the first quarter of 2004 as compared with the first quarter of 2003 (in thousands, except percentages).

The increase in research and development expense in the first quarter of 2004 compared to the first quarter of 2003 was primarily due to increased compensation costs of $0.4 million, outside services of $0.2 million for the development and qualification of fiber-to-the-premises, or FTTP, products, partially offset by lower depreciation of $0.2 million.

Selling, General and Administrative

Harmonic’s selling, general and administrative expense and the expense as a percentage of consolidated net sales in the first quarter of 2004 as compared with the corresponding prior year period are presented in the table below. Also presented is the related dollar and percentage increase (decrease) in selling, general and administrative expense in the first quarter of 2004 as compared with the first quarter of 2003 (in thousands, except percentages).

The increase in selling, general and administrative expense in the first quarter of 2004 compared to the first quarter of 2003 was due to an increase in selling costs of $0.9 million primarily in the CS division and increased general and administrative expenses of $1.0 million. The higher selling costs involved increased sales commissions and incentive compensation programs and travel expenses associated with increased sales, increased headcount and overall expense increases. The general and administrative expense increase was primarily due to increased corporate

15

governance costs of $0.4 million, higher compensation expenses of $0.2 million and a mediation settlement of $0.1 million. In addition, bad debt expenses in the first quarter of 2003 included a credit of approximately $0.5 million from the reversal of provisions recorded in 2002 arising from concerns about the financial condition of certain cable operators that subsequently were resolved.

Amortization of Intangibles

Harmonic’s amortization of intangibles expense and the expense as a percentage of consolidated net sales in the first quarter of 2004 as compared with the corresponding prior year period, are presented in the table below (in thousands, except percentages).

There was no change in amortization of intangibles between the first quarter of 2004 and 2003. Harmonic expects to record approximately $7.7 million in amortization of intangibles in operating expenses in 2004. In the first quarter of 2004 and 2003, approximately $1.5 million of amortization of intangibles was included in cost of sales.

Interest and Other Income, Net

Harmonic’s interest and other income, net, and interest and other income, net as a percentage of consolidated net sales in the first quarter of 2004 as compared with the corresponding prior year period are presented in the table below. Also presented is the related dollar and percentage increase (decrease) in interest and other income, net in the first quarter of 2004 as compared with the first quarter of 2003 (in thousands, except percentages).

The increase in the first quarter of 2004 compared to the first quarter of 2003 was due primarily to higher interest income of $0.3 million as a result of a higher cash, cash equivalents and investments balance in the first quarter of 2004 partially offset by lower foreign exchange gains of $0.2 million in the first quarter of 2004 compared to the first quarter of 2003 as a result of a stronger British pound against the U.S. dollar in the first quarter of 2004.

Income Taxes

Harmonic’s provision for income taxes, and provision for income taxes as a percentage of consolidated net sales in the first quarter of 2004 as compared with the corresponding prior year period are presented in the table below (in thousands, except percentages).

There was no change in the provision for income taxes in the first quarter of 2004 compared to the first quarter of 2003 due to foreign income taxes remaining the same.

16

Segments

Harmonic’s management uses income or loss from segment operations as its measure of segment profitability. Income or loss from segment operations excludes intangible amortization expense, corporate expenses, including excess facilities charges, and interest and other income, net. See Note 10 of Notes to Condensed Consolidated Financial Statements.

Fluctuations in net sales by operating segment are discussed more extensively in the section above entitled, Net Sales.

Harmonic’s income (loss) from segment operations and the income (loss) as a percentage of consolidated net sales in the first quarter as compared with the prior year, for each of the first quarter’s results are presented in the tables below. Also presented is the related dollar and percentage increase (decrease) in segment operations results in the first quarter of 2004 as compared with the first quarter of 2003 (in thousands, except percentages).

Convergent Systems (CS)

The increase in CS income from segment operations in the first quarter of 2004 compared to a loss in the first quarter of 2003 was primarily due to increased sales. Gross profit in the first quarter of 2004 increased primarily due to increased sales and lower product costs from third party manufacturers, and operating expenses increased compared to the first quarter of 2003 due to higher selling expenses and slightly higher research and development expenses.

Broadband Access Networks (BAN)

The increase in BAN income from segment operations in the first quarter of 2004 compared to a loss in the first quarter of 2003 was primarily due to increased sales. Gross profit in the first quarter of 2004 increased primarily due to increased sales and manufacturing efficiencies and operating expenses increased slightly compared to the first quarter of 2003. BAN results for the first quarter of 2004 include a benefit of $0.6 million related to products sold for which the cost basis had been written down in prior years.

Liquidity and Capital Resources

As of April 2, 2004, cash and cash equivalents, and short-term investments totaled $108.4 million compared to $112.6 million as of December 31, 2003. Cash used in operations was $4.4 million in the first three months of 2004, compared to $5.5 million in the first three months of 2003. The decreased use of cash in operations in the first three months of 2004 was primarily due to the lower net loss of $2.6 million and decreased accounts receivable of $6.3 million which was partially offset by higher inventory of $5.2 million and lower deferred revenue of $4.7 million. The decreased accounts receivable was primarily due to increased linearity of shipments throughout the first quarter of 2004. The higher inventory was primarily due to higher inventory purchases in order to meet anticipated demand and increased demonstration systems at customer locations.

On November 3, 2003, Harmonic completed a public offering of 9.0 million shares of its common stock at a price of $7.40 per share. The net proceeds were approximately $62.0 million, which is net of underwriters’ fees of $3.7 million, and related legal, accounting, printing and other expenses totaling approximately $0.9 million. In connection with this offering, the underwriters exercised their option to purchase 1.35 million additional shares of common stock at $7.40 per share on November 12, 2003 to cover over-allotments which resulted in additional net proceeds of approximately $9.4 million. The net proceeds from the offering are being used for general corporate purposes, including payment of existing liabilities, research and development, the development or acquisition of new products or technologies, equipment acquisitions, general working capital and operating expenses.

Under the terms of the merger agreement with C-Cube, Harmonic is generally liable for C-Cube’s pre-merger tax liabilities. Approximately $20.6 million of pre-merger tax liabilities remained outstanding at April 2, 2004 and are included in accrued liabilities. These liabilities represent estimates of C-Cube’s pre-merger tax obligations to various tax authorities in 13 countries. We are working with LSI Logic, which acquired the spun-off semiconductor business in June 2001 and assumed its obligations, to settle these obligations, a process which has been underway since the merger in 2000. Harmonic paid approximately $4.8 million of these tax obligations in April 2004, but is unable to predict when the remaining tax obligations will be paid, or in what amount. The full amount of the estimated obligation has been classified as a current liability. To the extent that these obligations are finally settled for less than the amounts provided, Harmonic is required, under the terms of the merger agreement, to refund the difference to LSI Logic. Conversely, if the settlements are more than the $20.6 million pre-merger tax liability, LSI is obligated to reimburse Harmonic.

Additions to property, plant and equipment were $1.6 million and $0.6 million in the first three months of 2004 and 2003, respectively. Harmonic currently expects capital expenditures to be less than $5 million during 2004.

Harmonic has a bank line of credit facility with Silicon Valley Bank, which provides for borrowings up to $13.5 million, including $3.5 million for equipment under a secured term loan. This facility, which was amended and restated in December 2003 and expires in December 2004, contains financial and other covenants, including the requirement for Harmonic to maintain cash, cash equivalents and short-term investments, net of credit extensions, of not less than $65.0 million. If Harmonic is unable to maintain this cash, cash equivalents and short-term investments balance or satisfy the additional affirmative covenant requirements, Harmonic would be in noncompliance with the facility. In the event of noncompliance by Harmonic with the covenants under the facility, Silicon Valley Bank would be entitled to exercise its remedies under the facility which include declaring all obligations immediately due and payable and disposing of the collateral if obligations were not repaid. At April 2, 2004, Harmonic was in compliance with the covenants under this line of credit facility. Future borrowings pursuant to the line bear interest at the bank’s prime rate or prime rate plus 1.0% (prime rate plus 0.5%-1.5% for equipment borrowings) depending upon the Company’s total cash position and previous six months’ revenue. Borrowings are payable monthly and are collateralized by all of Harmonic’s assets. As of April 2, 2004, $1.5 million was outstanding under the equipment term loan portion of this facility, of which $0.2 million was borrowed during the first quarter of 2004. The term loan is payable monthly, including principal and interest at 4.5% per annum on outstanding borrowings as of April 2, 2004 and matures at various dates through March 2007. Other than standby letters of credit and guarantees described in Note 12 of the unaudited condensed consolidated financial statements, there were no other outstanding borrowings or commitments under the line of credit facility as of April 2, 2004.

We currently believe that our existing liquidity sources, including the proceeds from the stock offering, and our bank line of credit will satisfy our cash requirements for at least the next twelve months, including the final settlement and payment of C-Cube’s pre-merger tax liabilities. However, we may need to raise additional funds if our expectations or estimates change or prove inaccurate, or to take advantage of unanticipated opportunities or to strengthen our financial position. The completed stock offering in November 2003 related to a registration statement on Form S-3 that was declared effective by the SEC in April 2002. The registration statement will continue to allow Harmonic to issue various types of securities, including common stock, preferred stock, debt securities, and warrants to purchase common stock from time to time, up to an aggregate of approximately $73 million, subject to market conditions and our capital needs.

In addition, from time to time, we review potential acquisitions that would complement our existing product offerings, enhance our technical capabilities or expand our marketing and sales presence. Any future transaction of

18

this nature could require potentially significant amounts of capital to finance the acquisition and related expenses as well as to integrate operations following a transaction, and could require us to issue our stock and dilute existing stockholders. If adequate funds are not available, or are not available on acceptable terms, we may not be able to take advantage of market opportunities, to develop new products or to otherwise respond to competitive pressures.

FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS

We Depend On Cable And Satellite Industry Capital Spending For A Substantial Portion Of Our Revenue And Any Decrease Or Delay In Capital Spending In These Industries Would Negatively Impact Our Resources, Operating Results And Financial Condition and Cash Flows.

Almost all of Harmonic’s sales have been derived from sales to cable television and satellite operators and we expect these sales to constitute a significant portion of net sales for the foreseeable future. Demand for our products will depend on the magnitude and timing of capital spending by cable television operators, satellite operators, broadcasters and telephone companies for constructing and upgrading of their systems.

These capital spending patterns are dependent on a variety of factors, including:

•		access to financing;
•		annual budget cycles;
•		the impact of industry consolidation;
•		the status of federal, local and foreign government regulation of telecommunications and television broadcasting;
•		overall demand for communication services and the acceptance of new video, voice and data services;
•		evolving industry standards and network architectures;
•		competitive pressures, including pricing pressures;
•		discretionary customer spending patterns; and
•		general economic conditions.

In the past, specific factors contributing to reduced capital spending have included:

•		uncertainty related to development of digital video and cable modem industry standards;
•		delays associated with the evaluation of new services and system architectures by many cable television operators;
•		emphasis on generating revenue from existing customers by cable television operators instead of new construction or network upgrades;
•		proposed business combinations by our customers and regulatory review thereof;
•		economic and financial conditions in domestic and international markets; and
•		bankruptcies and financial restructuring of major customers.

The prolonged economic recession, the financial difficulties of certain of our customers and changes in our customers’ deployment plans adversely affected our business in the latter part of 2001, throughout 2002 and in the

19

first half of 2003. Two of our major domestic customers, Adelphia Communications and Winfirst, declared bankruptcy during the first half of 2002, while NTL, a major international customer, emerged from bankruptcy in 2003. Furthermore, we believe that our net sales to satellite customers were adversely affected by the uncertainty related to the prolonged regulatory review of the proposed acquisition of DIRECTV by EchoStar in 2002. These events, coupled with uncertain and volatile capital markets, also pressured the market values of domestic cable operators and restricted their access to capital. This reduced access to funding for new and existing customers caused delays in the timing and scale of deployments of our equipment and also resulted in the postponement or cancellation of certain projects by our customers. Several customers also canceled new projects or delayed new orders to allow them to reduce inventory levels that were in excess of their deployment requirements. We believe that these factors contributed to decreased net sales in both our CS division and our BAN division during the second half of 2002 and the first half of 2003 compared to the first half of 2002.

We believe that the financial condition of many of our customers has stabilized or improved, and our net sales increased sequentially in the second, third and fourth quarters of 2003 and increased in the first quarter of 2004 compared to the first quarter of 2003. However, another economic downturn or weakness in capital markets could cause additional financial difficulties among our customers, and customers whose financial condition has stabilized may not purchase new equipment at levels we have seen in the past. Continued financial difficulties among our customers would adversely affect our operating results and financial condition. Also, The News Corporation Ltd. recently acquired an indirect controlling interest in Hughes Electronics, the parent company of DIRECTV. We cannot currently predict the impact of The News Corporation Ltd.’s control of DIRECTV on our future sales. As a result, we cannot assure you that our net sales growth will continue.

Major US cable operators have indicated that the imminent completion of major network upgrades, which involve significant labor and construction costs, will lead to lower capital expenditures in the future. If our product portfolio and product development plans do not position us well to capture an increased portion of the expected reduced capital spending of US cable operators, our revenue may decline and our operating results would be adversely affected.

Our Customer Base Is Concentrated And The Loss Of One Or More Of Our Key Customers Would Harm Our Business. The Loss Of Any Key Customer Would Have A Negative Effect On Our Business.

Historically, a majority of our sales have been to relatively few customers, due in part to the consolidation of ownership of cable television and direct broadcast satellite systems, and we expect this customer concentration to continue in the foreseeable future. Sales to our ten largest customers in the first quarter of 2004, and the years 2003 and 2002, accounted for approximately 61%, 65% and 61% of net sales, respectively. Although we are attempting to broaden our customer base by penetrating new markets such as the telecommunications and broadcast markets and expand internationally, we expect to see continuing industry consolidation and customer concentration due in part to the significant capital costs of constructing broadband networks. For example, Comcast acquired AT&T Broadband in November 2002, thereby creating the largest U.S. cable operator, reaching approximately 22 million subscribers. In the DBS segment, The News Corporation Ltd. recently acquired an indirect controlling interest in Hughes Electronics, the parent company of DIRECTV. In addition, financial restructurings or mergers of companies such as Adelphia Communications and several European operators may lead to further industry consolidation. In the first quarter of 2004, sales to Comcast Cable, Echostar Satellite Corp. and Cox Communications accounted for 14%, 14% and 13% of net sales, respectively. In 2003, sales to Comcast accounted for 32% of net sales. In 2002, sales to Charter Communications and Comcast accounted for 18% and 10% of net sales. If Comcast and AT&T Broadband had been combined for all of 2002, total revenues would have been 17% of net sales. The loss of any significant customer or any reduction in orders by any significant customer, or our failure to qualify our products with a significant customer could adversely affect our business, operating results and liquidity. In this regard, sales to Charter Communications were significantly lower in 2003 than in 2002, both in absolute dollars and as a percentage of revenue, as they have significantly reduced capital spending. The loss of, or any reduction in orders from, a significant customer would harm our business.

20

Our Operating Results Are Likely To Fluctuate Significantly And May Fail To Meet Or Exceed The Expectations Of Securities Analysts Or Investors, Causing Our Stock Price To Decline.

Our operating results have fluctuated in the past and are likely to continue to fluctuate in the future, on an annual and a quarterly basis, as a result of several factors, many of which are outside of our control. Some of the factors that may cause these fluctuations include:

•		the level and timing of capital spending of our customers, both in the U.S. and in foreign markets;
•		changes in market demand;
•		the timing and amount of orders, especially from significant customers;
•		the timing of revenue from systems contracts which may span several quarters;
•		competitive market conditions, including pricing actions by our competitors;
•		seasonality, with fewer construction and upgrade projects typically occurring in winter months and otherwise being affected by inclement weather;
•		our unpredictable sales cycles;
•		new product introductions by our competitors or by us;
•		changes in domestic and international regulatory environments;
•		market acceptance of new or existing products;
•		the cost and availability of components, subassemblies and modules;
•		the mix of our customer base and sales channels;
•		the mix of our products sold;
•		our development of custom products and software;
•		the level of international sales; and
•		economic and financial conditions specific to the cable and satellite industries, and general economic conditions.

For example, the timing of deployment of our equipment can be subject to a number of other risks, including the availability of skilled engineering and technical personnel, the availability of other equipment such as digital set top boxes, and the need for local franchise and licensing approvals.

In addition, we often recognize a substantial portion of our revenues in the last month of the quarter. We establish our expenditure levels for product development and other operating expenses based on projected sales levels, and expenses are relatively fixed in the short term. Accordingly, variations in timing of sales can cause significant fluctuations in operating results. As a result of all these factors, our operating results in one or more future periods may fail to meet or exceed the expectations of securities analysts or investors. In that event, the trading price of our common stock would likely decline. In this regard, due to lower than expected sales in several quarters during 2000 and 2001, and during the third quarter of 2002 and the first quarter of 2003, we failed to meet our internal expectations, as well as the expectations of securities analysts and investors, and the price of our common stock declined, in some cases significantly.

21

Our Future Growth Depends on Market Acceptance of Several Emerging Broadband Services, on the Adoption of New Broadband Technologies and on Several Other Broadband Industry Trends.

Future demand for our products will depend significantly on the growing market acceptance of several emerging broadband services, including digital video; video-on-demand (VOD); high definition (HD) television; very high-speed data services and voice-over-IP (VoIP) telephony. The effective delivery of these services will depend in part on a variety of new network architectures, such as fiber-to-the premises (FTTP) networks; new video compression standards such as MPEG-4 and Microsoft’s Windows Media 9; the greater use of protocols such as IP; and the introduction of new consumer devices, such as advanced set-top boxes and personal video recorders (PVRs). If adoption of these emerging services and/or technologies is not as widespread or as rapid as we expect, our net sales growth will be materially and adversely affected.

Furthermore, other technological, industry and regulatory trends will affect the growth of our business. These trends include the following:

•		convergence, or the desire of certain network operators to deliver a package of video, voice and data services to consumers, also known as the “triple play”;
•		the use of digital video by businesses, governments and educators;
•		the privatization of state-owned telcos around the world;
•		efforts by regulators and governments in the United States and abroad to encourage the adoption of broadband and digital technologies; and
•		the extent and nature of regulatory attitudes towards such issues as competition between operators, access by third parties to networks of other operators, and new services such as VoIP.

If, for instance, operators do not pursue the triple play as aggressively as we expect, our net sales growth would be materially and adversely affected. Similar, if our expectations regarding these and other trends are not met, our net sales may be materially and adversely affected.

If Sales Forecasted For A Particular Period Are Not Realized In That Period Due To The Unpredictable Sales Cycles Of Our Products, Our Operating Results For That Period Will Be Harmed.

The sales cycles of many of our products, particularly our newer products and products sold internationally, are typically unpredictable and usually involve:

•		a significant technical evaluation;
•		a commitment of capital and other resources by cable, satellite, and other network operators;
•		time required to engineer the deployment of new technologies or new broadband services;
•		testing and acceptance of new technologies that affect key operations; and
•		test marketing of new services with subscribers.

For these and other reasons, our sales cycles generally last three to six months, but can last up to 12 months. If orders forecasted for a specific customer for a particular quarter do not occur in that quarter, our operating results for that quarter could be substantially lower than anticipated.

A significant portion of our revenue is derived from solution contracts that include a combination of product sales as well as design, installation and integration services. Revenue forecasts for solution contracts are based on the estimated timing of the design, installation and integration of projects. Because the solution contracts generally span several quarters and revenue recognition is based on progress under the contract, the timing of revenue is difficult to predict and could result in lower than expected revenue in any particular quarter. In addition, new products may include elements, such as a more significant software component than our existing products, which may impact the recognition of revenue and result in the deferral of revenue until all elements of the arrangement are satisfied.

22

We Depend On Our International Sales And Are Subject To The Risks Associated With International Operations, Which May Negatively Affect Our Operating Results.

Sales to customers outside of the United States in the first quarter of 2004, and the years 2003 and 2002 represented 33%, 29% and 29%, of net sales, respectively, and we expect that international sales will continue to represent a meaningful portion of our net sales for the foreseeable future. Furthermore, a substantial portion of our contract manufacturing occurs overseas. Our international operations, the international operations of our contract manufacturers, and our efforts to increase sales in international markets, are subject to a number of risks, including:

•		changes in foreign government regulations and telecommunications standards;
•		import and export license requirements, tariffs, taxes and other trade barriers;
•		fluctuations in currency exchange rates;
•		difficulty in collecting accounts receivable;
•		the burden of complying with a wide variety of foreign laws, treaties and technical standards;
•		difficulty in staffing and managing foreign operations;
•		political and economic instability; and
•		changes in economic policies by foreign governments.

Certain of our international customers have accumulated significant levels of debt and have announced during the past three years reorganizations and financial restructurings, including bankruptcy filings. Even if these restructurings are completed, we cannot assure you that these customers will be in a position to purchase new equipment at levels we have seen in the past.

While our international sales and operating expenses have typically been denominated in U.S. dollars, fluctuations in currency exchange rates could cause our products to become relatively more expensive to customers in a particular country, leading to a reduction in sales or profitability in that country.

Following implementation of the Euro in January 2002, a higher portion of our European business is denominated in Euros, which may subject us to increased foreign currency risk. Gains and losses on the conversion to U.S. dollars of accounts receivable, accounts payable and other monetary assets and liabilities arising from international operations may contribute to fluctuations in operating results. Furthermore, payment cycles for international customers are typically longer than those for customers in the United States. Unpredictable sales cycles could cause us to fail to meet or exceed the expectations of security analysts and investors for any given period. In addition, foreign markets may not develop in the future.

If Demand For Our Products Increases More Quickly Than We Expect, We May Be Unable To Meet Our Customers’ Requirements.

Our net sales increased sequentially in the second, third and fourth quarters of 2003 and increased in the first quarter of 2004 compared to the first quarter of 2003. If demand for our products continues to increase, the difficulty of accurately forecasting our customers’ requirements and meeting these requirements will increase. Forecasting to meet customers’ needs is particularly difficult in connection with newer products. Our ability to meet customer demand depends significantly on the availability of components and other materials as well as the ability of our contract manufacturers to scale their production. From time to time, we assess our relationship with our contract manufacturers. Changes in these relationships, including our recent agreement with Plexus, or reallocating manufacturing to new or existing contract manufacturers, could adversely affect our ability to meet our customers’ requirements in a timely manner, if at all, and could create operating inefficiencies. Furthermore, we purchase several key components, subassemblies and modules used in the manufacture or integration of our products from sole or limited sources and any disruption in our relationship with these providers or in the ability of such providers to satisfy our requirements could adversely affect our ability to deliver our products to customers.

23

Also, in recent years, in response to lower net sales and the prolonged economic recession, we significantly reduced our headcount and other expenses. As a result, we may be unable to respond to customer demand that increases more quickly than we expect. If we fail to meet customers’ supply expectations, our net sales would be adversely affected and we may lose business.

Competition For Qualified Personnel, Particularly Management Personnel, Can Be Intense. In Order To Manage Our Growth, We Must Be Successful In Addressing Management Succession Issues And Attracting And Retaining Qualified Personnel.

Our future success will depend, to a significant extent, on the ability of our management to operate effectively, both individually and as a group. We must successfully manage transition and replacement issues that may result from the departure or retirement of members of our senior management. We are dependent on our ability to retain and motivate high caliber personnel, in addition to attracting new personnel. Competition for qualified management, technical and other personnel can be intense, and we may not be successful in attracting and retaining such personnel. Competitors and others have in the past and may in the future attempt to recruit our employees. While our employees are required to sign standard agreements concerning confidentiality and ownership of inventions, we generally do not have employment contracts or non-competition agreements with any of our personnel. The loss of the services of any of our key personnel, the inability to attract or retain qualified personnel in the future or delays in hiring required personnel, particularly senior management and engineers and other technical personnel, could negatively affect our business.

We Face Risks Associated With Having Important Facilities And Resources Located In Israel.

Harmonic maintains a facility in Caesarea in the State of Israel with a total of approximately 60 employees as of April 2, 2004, or approximately 11% of our workforce. The employees at this facility consist principally of research and development personnel involved in development of certain products for the CS division. In addition, we have pilot production capabilities at this facility consisting of procurement of subassemblies and modules from Israeli subcontractors and final assembly and test operations. Accordingly, we are directly influenced by the political, economic and military conditions affecting Israel, and any major hostilities involving Israel or the interruption or curtailment of trade between Israel and its trading partners could significantly harm our business. The September 2001 terrorist attacks, the ongoing U.S. war on terrorism and the escalation of terrorist attacks and hostilities within Israel have heightened these risks. We cannot assure you that the protraction or escalation of current tensions in the Middle East will not adversely affect our business and results of operations.

In addition, most of our employees in Israel are currently obligated to perform annual reserve duty in the Israel Defense Forces and several have been called for active military duty recently. We cannot predict the effect of these obligations on Harmonic in the future.

Financial, Regulatory and Other Issues Among Our Customers Could Adversely Affect Our Business.

The telecommunications industry has been particularly impacted by the prolonged economic recession, adverse conditions in capital markets and financial difficulties in both the service and equipment sectors, including bankruptcies. Although large telecommunications service providers such as WorldCom (now MCI) and troubled data and voice-oriented start-ups have not been traditional customers of Harmonic, the cable, satellite and broadcast sectors have experienced significant financial problems. Many of our domestic and international customers have accumulated significant levels of debt and have announced reorganizations and financial restructurings during the past three years, including bankruptcy filings. In particular, Adelphia Communications, a major domestic cable operator, declared bankruptcy in June 2002. The stock prices of other domestic cable companies came under pressure following the Adelphia bankruptcy due to concerns about debt levels and capital expenditure requirements for new and expanded services, thereby making the raising of capital more difficult and expensive. New operators, such as RCN and WinFirst, also had difficulty in accessing capital markets. WinFirst subsequently filed for bankruptcy and RCN has entered into forbearance agreements with certain of its lenders. In Europe, rapid consolidation of the cable industry through acquisition also led to significant levels of debt at the major MSOs, and companies such as NTL and UPC commenced bankruptcy proceedings. European digital broadcasters, such as ITV Digital, Kirsch and Quiero, have also filed for protection from creditors.

24

While the capital market concerns about the domestic cable industry have eased since the summer of 2002, market conditions remain difficult and capital spending plans are generally constrained. It is likely that further industry restructuring will take place via mergers or spin-offs, such as the completed Comcast/AT&T Broadband transaction, the proposed spin-off of Time-Warner Cable from Time-Warner and the proposed sale of Adelphia Communications requested by its creditors. Also, The News Corporation Ltd., in December 2003, acquired an indirect controlling interest in Hughes Electronics, the parent company of DIRECTV. This transaction followed regulatory opposition to the proposed acquisition of DIRECTV by EchoStar. We cannot currently predict the impact of The News Corporation Ltd. control of DIRECTV on our future sales. We believe that uncertainty during 2002 regarding the proposed DIRECTV and EchoStar merger adversely affected capital spending by both of these parties as well as other customers. In addition, further business combinations may occur in the satellite industry, and these further combinations could adversely affect our business. Regulatory issues, financial concerns and business combinations among our customers are likely to significantly affect the industry, its capital spending plans, and our levels of business for the foreseeable future.

We Must Be Able To Manage Expenses And Inventory Risks Associated With Meeting The Demand Of Our Customers.

If actual orders are materially lower than the indications we receive from our customers, our ability to manage inventory and expenses may be affected. If we enter into purchase commitments to acquire materials, or expend resources to manufacture products, and such products are not purchased by our customers, our business and operating results could suffer. In this regard, our gross margins and operating results for the fourth quarter of 2000 and in 2001 were adversely affected by provisions for excess and obsolete inventories of approximately $49 million.

The Markets In Which We Operate Are Intensely Competitive And Many Of Our Competitors Are Larger And More Established.

The markets for cable television fiber optics systems and digital video broadcasting systems are extremely competitive and have been characterized by rapid technological change and declining average selling prices. Pressure on average selling prices has been particularly severe during the recent economic downturn as equipment suppliers compete aggressively for customers’ reduced capital spending. Harmonic’s competitors in the cable television fiber optics systems business include corporations such as C-Cor.net, Motorola, and Scientific-Atlanta. In the digital and video broadcasting systems business, we compete broadly with vertically integrated system suppliers including Motorola, Scientific-Atlanta, Tandberg Television and Thomson Multimedia, and in certain product lines with Cisco and a number of smaller companies.

Many of our competitors are substantially larger and have greater financial, technical, marketing and other resources than Harmonic. Many of these large organizations are in a better position to withstand any significant reduction in capital spending by customers in these markets. They often have broader product lines and market focus and may not be as susceptible to downturns in a particular market. In addition, many of our competitors have been in operation longer than we have and therefore have more long standing and established relationships with domestic and foreign customers. We may not be able to compete successfully in the future, which may harm our business.

If any of our competitors’ products or technologies were to become the industry standard, our business could be seriously harmed. For example, U.S. cable operators have to date mostly purchased proprietary digital systems from Motorola and Scientific-Atlanta. While certain operators have made limited purchases of the “open” systems provided by Harmonic, we cannot assure you that our digital products will find broad market acceptance with U.S. cable operators. In addition, companies that have historically not had a large presence in the broadband communications equipment market have begun recently to expand their market share through mergers and acquisitions. The continued consolidation of our competitors could have a significant negative impact on us. Further, our competitors, particularly competitors of our digital and video broadcasting systems business, may bundle their products or incorporate functionality into existing products in a manner that discourages users from purchasing our products or which may require us to lower our selling prices resulting in lower gross margins.

25

Broadband Communications Markets Are Characterized By Rapid Technological Change.

Broadband communications markets are relatively immature, making it difficult to accurately predict the markets’ future growth rates, sizes or technological directions. In view of the evolving nature of these markets, it is possible that cable television operators, telephone companies or other suppliers of broadband wireless and satellite services will decide to adopt alternative architectures or technologies that are incompatible with our current or future products. If we are unable to design, develop, manufacture and sell products that incorporate or are compatible with these new architectures or technologies, our business will suffer. Also, decisions by customers to adopt new technologies or products are often delayed by extensive evaluation and qualifications processes and can result in delays of current products.

We Need To Develop And Introduce New And Enhanced Products In A Timely Manner To Remain Competitive.

Broadband communications markets are characterized by continuing technological advancement, changes in customer requirements and evolving industry standards. To compete successfully, we must design, develop, manufacture and sell new or enhanced products that provide increasingly higher levels of performance and reliability. However, we may not be able to successfully develop or introduce these products if our products:

•		are not cost effective;
•		are not brought to market in a timely manner;
•		are not in accordance with evolving industry standards and architectures; or
•		fail to achieve market acceptance, or are ahead of the market.

Also, to successfully develop and market certain of our planned products for digital applications, we may be required to enter into technology development or licensing agreements with third parties. We cannot assure you that we will be able to enter into any necessary technology development or licensing agreement on terms acceptable to us, or at all. The failure to enter into technology development or licensing agreements when necessary could limit our ability to develop and market new products and, accordingly, could materially and adversely affect our business and operating results.

Our BAN division is currently marketing products for FTTP networks which major telcos have announced that they intend to build. Although we believe that a number of our existing products can be deployed successfully in these networks, we may need to devote considerable resources to negotiating contracts, qualifying our products, hiring knowledgeable personnel, and may make significant financial commitments. There can be no assurance that these efforts will be successful in the near future, or at all.

We Purchase Several Key Components, Subassemblies And Modules Used In The Manufacture Or Integration Of Our Products From Sole Or Limited Sources, And We Are Increasingly Dependent On Contract Manufacturers.

Many components, subassemblies and modules necessary for the manufacture or integration of our products are obtained from a sole supplier or a limited group of suppliers. Our reliance on sole or limited suppliers, particularly foreign suppliers, and our increased reliance on subcontractors since the merger with C-Cube involves several risks, including a potential inability to obtain an adequate supply of required components, subassemblies or modules and reduced control over pricing, quality and timely delivery of components, subassemblies or modules. In particular, certain optical components have in the past been in short supply and are available only from a small number of suppliers, including sole source suppliers. While we expend resources to qualify additional optical component sources, consolidation of suppliers in the industry and the small number of viable alternatives have limited the results of these efforts. We do not generally maintain long-term agreements with any of our suppliers. Managing our supplier and contractor relationships is particularly difficult during time periods in which we introduce new products and during time periods in which demand for our products is increasing, especially if demand increases more quickly than we expect. Furthermore, from time to time we assess our relationship with our contract manufacturers. In late 2003, we entered into a three-year agreement with Plexus Services Corp. as our primary contract

26

manufacturer. The transition of our manufacturing requirements from certain current contract manufacturers to Plexus is in progress. We plan to complete the transition during the second quarter of 2004. Difficulties in managing relationships with current contract manufacturers, or problems encountered by Plexus or Harmonic in completing the transition, could impede our ability to meet our customers’ requirements and adversely affect our operating results. An inability to obtain adequate deliveries or any other circumstance that would require us to seek alternative sources of supply could affect our ability to ship our products on a timely basis, which could damage relationships with current and prospective customers and harm our business. We attempt to limit this risk by maintaining safety stocks of certain components, subassemblies and modules. As a result of this investment in inventories, we have in the past and in the future may be subject to risk of excess and obsolete inventories, which could harm our business, operating results, financial position and liquidity. In this regard, our gross margins and operating results from the fourth quarter of 2000 through the third quarter of 2001 were adversely affected by excess and obsolete inventory charges of approximately $49 million.

We May Need Additional Capital In The Future And May Not Be Able To Secure Adequate Funds On Terms Acceptable To Us.

We have generated substantial operating losses since we began operations in June 1988. The extent of our future losses and the timing of potential profitability are highly uncertain, and we may never achieve sustained profitable operations. We have been engaged in the design, manufacture and sale of a variety of broadband products since inception, which has required, and will continue to require, significant research and development expenditures. As of April 2, 2004 we had an accumulated deficit of $1.9 billion. These losses, among other things, have had and may have an adverse effect on our stockholders’ equity and working capital.

We believe that the proceeds of the stock offering we completed in November 2003, together with our existing liquidity sources, will satisfy our cash requirements for at least the next twelve months, including the final settlement and payment of C-Cube’s pre-merger tax liabilities. However, we may need to raise additional funds if our expectations are incorrect, to fund our operations, to take advantage of unanticipated opportunities or to strengthen our financial position. The stock offering we completed in November 2003 related to a registration statement on Form S-3 declared effective by the SEC in April 2002. This registration statement will continue to allow Harmonic to issue various types of securities, including common stock, preferred stock, debt securities and warrants to purchase common stock from time to time, up to an aggregate of approximately $73 million, subject to market conditions and our capital needs. Our ability to raise funds may be adversely affected by a number of factors relating to Harmonic, as well as factors beyond our control, including conditions in capital markets and the cable, telecom and satellite industries. There can be no assurance that such financing will be available on terms acceptable to us, if at all.

In addition, from time to time, we review potential acquisitions that would complement our existing product offerings, enhance our technical capabilities or expand our marketing and sales presence. Any future transaction of this nature could require potentially significant amounts of capital to finance the acquisition and related expenses as well as to integrate operations following a transaction, and could require us to issue our stock and dilute existing stockholders. If adequate funds are not available, or are not available on acceptable terms, we may not be able to take advantage of market opportunities, to develop new products or to otherwise respond to competitive pressures.

We may raise additional financing through public or private equity offerings, debt financings or additional corporate collaboration and licensing arrangements. To the extent we raise additional capital by issuing equity securities, our stockholders may experience dilution. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or products, or grant licenses on terms that are not favorable to us. If adequate funds are not available, we will not be able to continue developing our products.

We Need To Effectively Manage Our Operations And The Cyclical Nature Of Our Business.

The cyclical nature of our business has placed, and is expected to continue to place, a significant strain on our personnel, management and other resources. This strain has been exacerbated by the acquisition of DiviCom and the subsequent loss of numerous employees, including senior management. In addition, we reduced our work force by approximately 44% between December 31, 2000 and December 31, 2003 due to reduced industry spending and

27

demand for our products. If demand for products increases significantly, we may need to increase our headcount. Our ability to manage our business effectively in the future, including any future growth, will require us to train, motivate and manage our employees successfully, to attract and integrate new employees into our overall operations, to retain key employees and to continue to improve our operational, financial and management systems.

We Are Incurring Additional Costs And Devoting More Management Resources To Comply With Increasing Regulation Of Corporate Governance And Disclosure.

We are spending an increased amount of management time and external resources to understand and comply with changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations and Nasdaq Stock Market rules. Devoting the necessary resources to comply with evolving corporate governance and public disclosure standards has resulted in increased general and administrative expenses and a diversion of management time and attention to compliance activities. Moreover, we may not be able to comply with these new rules and regulations on a timely basis.

Recent And Proposed Regulations Related To Equity Compensation Could Adversely Affect Earnings, Affect Our Ability To Raise Capital And Affect Our Ability To Attract And Retain Key Personnel.

Since our inception, we have used stock options as a fundamental component of our employee compensation packages. We believe that our stock option plans are an essential tool to link the long-term interests of stockholders and employees, especially executive management, and serve to motivate management to make decisions that will, in the long run, give the best returns to stockholders. The Financial Accounting Standards Board (FASB) has proposed changes to the United States generally accepted accounting principles, or US GAAP, that, if implemented, would require us to record a charge to earnings for employee stock option grants, as well as other equity-based awards. This proposed accounting pronouncement would negatively impact our earnings and could affect our ability to raise capital on acceptable terms. In addition, new regulations implemented by The Nasdaq National Market requiring stockholder approval for all stock option plans could make it more difficult for us to grant options to employees in the future. To the extent that new regulations make it more difficult or expensive to grant options to employees, we may incur increased compensation costs, change our equity compensation strategy or find it difficult to attract, retain and motivate employees, each of which could materially and adversely affect our business.

We Are Liable For C-Cube’s Pre-Merger Tax Liabilities, Including Tax Liabilities Resulting From The Spin-Off Of Its Semiconductor Business.

Under the terms of the merger agreement with C-Cube, Harmonic is generally liable for C-Cube’s pre-merger tax liabilities. Approximately $20.6 million of pre-merger tax liabilities remained outstanding at April 2, 2004 and are included in accrued liabilities. We are working with LSI Logic, which acquired C-Cube’s spun-off semiconductor business in June 2001 and assumed its obligations, to settle these obligations, a process which has been underway since the merger in 2000. These liabilities represent estimates of C-Cube’s pre-merger tax obligations to various tax authorities in 13 countries. Harmonic paid approximately $4.8 million of these tax obligations in April 2004, but is unable to predict when the remaining tax obligations will be paid, or in what amount. The full amount of the estimated obligation has been classified as a current liability. To the extent that these obligations are finally settled for less than the amounts provided, Harmonic is required, under the terms of the merger agreement, to refund the difference to LSI Logic. Conversely, if the settlements are more than the $20.6 million pre-merger tax liability, LSI Logic is obligated to reimburse Harmonic.

The merger agreement stipulates that Harmonic will be indemnified by the spun-off semiconductor business if the cash reserves are not sufficient to satisfy all of C-Cube’s tax liabilities for periods prior to the merger. If for any reason, the spun-off semiconductor business does not have sufficient cash to pay such taxes, or if there are additional taxes due with respect to the non-semiconductor business and Harmonic cannot be indemnified by LSI Logic, Harmonic generally will remain liable, and such liability could have a material adverse effect on our financial condition, results of operations or cash flows.

28

We May Be Subject To Risks Associated With Other Acquisitions.

We have made, continue to consider making and may make investments in complementary companies, products or technologies. If we enter into acquisition transactions, we could have difficulty assimilating or retaining the acquired companies’ key personnel and operations or integrating the acquired technology or products into ours. We also may face challenges in achieving the strategic objectives, cost savings or other benefits from a proposed acquisition and difficulties in expanding our management information systems to accommodate the acquired business. These difficulties could disrupt our ongoing business, distract our management and employees and significantly increase our expenses. Moreover, our operating results may suffer because of acquisition-related expenses, amortization of intangible assets and impairment of acquired goodwill or intangible assets. Furthermore, we may have to incur debt or issue equity securities to pay for any future acquisitions, or to provide for additional working capital requirements, the issuance of which could be dilutive to our existing shareholders. If we are unable to successfully address any of these risks, our business, financial condition and operating results could be harmed.

Cessation Of The Development And Production Of Video Encoding Chips By C-Cube’s Spun-off Semiconductor Business May Adversely Impact Us.

The DiviCom business and C-Cube semiconductor business collaborated on the production and development of two video encoding microelectronic chips prior to the merger. In connection with the merger, Harmonic and the spun-off semiconductor business entered into a contractual relationship under which Harmonic will have access to certain of the spun-off semiconductor business technologies and products which the DiviCom business previously depended for its product and service offerings. This agreement expires in October 2004. The spun-off semiconductor business is the sole supplier of these chips to Harmonic. Several of these products continue to be important to our business, and we have incorporated these chips into additional products that we have developed.

However, under the contractual relationships between Harmonic and the spun-off semiconductor business, which was acquired by LSI Logic in June 2001, the semiconductor business does not have a firm commitment to continue the development of video encoding microelectronic chips. As a result, the semiconductor business may choose not to continue future development of the chips for any reason. The semiconductor business may also encounter in the future technological difficulties in the production and development of the chips. If the spun-off semiconductor business is not able to or does not sustain its development and production efforts in this area our business, financial condition, results of operations or cash flow could be harmed.

Our Failure To Adequately Protect Our Proprietary Rights May Adversely Affect Us.

We currently hold 39 issued United States patents and 12 issued foreign patents, and have a number of patent applications pending. Although we attempt to protect our intellectual property rights through patents, trademarks, copyrights, licensing arrangements, maintaining certain technology as trade secrets and other measures, we cannot assure you that any patent, trademark, copyright or other intellectual property rights owned by us will not be invalidated, circumvented or challenged, that such intellectual property rights will provide competitive advantages to us or that any of our pending or future patent applications will be issued with the scope of the claims sought by us, if at all. We cannot assure you that others will not develop technologies that are similar or superior to our technology, duplicate our technology or design around the patents that we own. In addition, effective patent, copyright and trade secret protection may be unavailable or limited in certain foreign countries in which we do business or may do business in the future.

We believe that patents and patent applications are not currently significant to our business, and investors therefore should not rely on our patent portfolio to give us a competitive advantage over others in our industry. We believe that the future success of our business will depend on our ability to translate the technological expertise and innovation of our personnel into new and enhanced products. We generally enter into confidentiality or license agreements with our employees, consultants, vendors and customers as needed, and generally limit access to and distribution of our proprietary information. Nevertheless, we cannot assure you that the steps taken by us will prevent misappropriation of our technology. In addition, we have taken in the past, and may take in the future, legal action to enforce our patents and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement or invalidity. Such

29

litigation could result in substantial costs and diversion of resources and could negatively affect our business, operating results, financial position or cash flows.

In order to successfully develop and market certain of our planned products for digital applications, we may be required to enter into technology development or licensing agreements with third parties. Although many companies are often willing to enter into technology development or licensing agreements, we cannot assure you that such agreements will be negotiated on terms acceptable to us, or at all. The failure to enter into technology development or licensing agreements, when necessary, could limit our ability to develop and market new products and could cause our business to suffer.

We Or Our Customers May Face Intellectual Property Infringement Claims From Third Parties.

Harmonic’s industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. In particular, leading companies in the telecommunications industry have extensive patent portfolios. From time to time, third parties, including these leading companies, have asserted and may assert exclusive patent, copyright, trademark and other intellectual property rights against us or our customers. Indeed, a number of third parties, including leading companies, have asserted patent rights to technologies that are important to us.

Our suppliers and customers may receive similar claims. We have agreed to indemnify some of our suppliers and customers for alleged patent infringement. The scope of this indemnity varies, but, in some instances, includes indemnification for damages and expenses (including reasonable attorney’s fees). In this regard, since December 2000, we have been in communication with several of Harmonic’s customers who have been contacted by one of these leading companies that believes certain of our products require a license under a number of their patents. We currently are reviewing the identified patents to examine whether we consider a license necessary. While it is our understanding that the third party is willing to grant our customers a non-exclusive license under the identified patents, there can be no assurance that the terms of any offered license would be acceptable to our customers or that failure to obtain a license or the costs associated with any license would not cause our operating results to be materially adversely affected.

On July 3, 2003, Stanford University and Litton Systems filed a complaint in U.S. District Court for the Central District of California alleging that optical fiber amplifiers incorporated into certain of Harmonic’s products infringe U.S. Patent No. 4,859,016. This patent expired in September 2003. The complaint seeks injunctive relief, royalties and damages. Harmonic has not been served in the case. Harmonic is currently evaluating its position with respect to this patent and has engaged in discussions with the plaintiff regarding potential settlement of the matter. At this time, Harmonic is unable to determine whether Harmonic will be able to settle this matter on reasonable terms or at all, nor can Harmonic predict the impact of an adverse outcome of this litigation if Harmonic elects to defend against it. Consequently, Harmonic has made no provision in its financial statements for the outcome of a negotiated settlement or an unfavorable verdict in litigation. An unfavorable outcome of this matter could have a material adverse effect on Harmonic’s business, operating results, financial position or cash flows.

We Are The Subject Of Securities Class Action Claims And Other Litigation Which, If Adversely Determined, Could Harm Our Business And Operating Results.

Between June 28 and August 25, 2000, several actions alleging violations of the federal securities laws by Harmonic and certain of its officers and directors (some of whom are no longer with Harmonic) were filed in or removed to the United States District Court for the Northern District of California. The actions subsequently were consolidated. A consolidated complaint, filed on December 7, 2000, was brought on behalf of a purported class of persons who purchased Harmonic’s publicly traded securities between January 19 and June 26, 2000. The complaint also alleged claims on behalf of a purported subclass of persons who purchased C-Cube securities between January 19 and May 3, 2000. In addition to Harmonic and certain of its officers and directors, the complaint also named C-Cube Microsystems Inc. and several of its officers and directors as defendants. The complaint alleged that, by making false or misleading statements regarding Harmonic’s prospects and customers and its acquisition of C-Cube, certain defendants violated sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The complaint also alleged that certain defendants violated section 14(a) of the Exchange Act and sections 11, 12(a)(2), and 15 of the Securities Act

30

of 1933 by filing a false or misleading registration statement, prospectus, and joint proxy in connection with the C-Cube acquisition.

On July 3, 2001, the Court dismissed the consolidated complaint with leave to amend. An amended complaint alleging the same claims against the same defendants was filed on August 13, 2001. Defendants moved to dismiss the amended complaint on September 24, 2001. On November 13, 2002, the Court issued an opinion granting the motions to dismiss the amended complaint without leave to amend. Judgment for defendants was entered on December 2, 2002. On December 12, 2002, plaintiffs filed a motion to amend the judgment and for leave to file an amended complaint pursuant to Rules 59(e) and 15(a) of the Federal Rules of Civil Procedure. On June 6, 2003, the Court denied plaintiffs’ motion to amend the judgment and for leave to file an amended complaint. Plaintiffs filed a notice of appeal on July 1, 2003. Plaintiffs filed their opening brief on December 3, 2003. Defendants filed their answering briefs on March 2, 2004. Plaintiffs’ reply brief was filed on April 16, 2004. No hearing has been scheduled yet.

A derivative action purporting to be on behalf of Harmonic was filed against its then-current directors in the Superior Court for the County of Santa Clara on September 5, 2000. Harmonic also was named as a nominal defendant. The complaint is based on allegations similar to those found in the securities class action and claims that the defendants breached their fiduciary duties by, among other things, causing Harmonic to violate federal securities laws. The derivative action was removed to the United States District Court for the Northern District of California on September 20, 2000. All deadlines in this action were stayed pending resolution of the motions to dismiss the securities class action. On July 29, 2003, the Court approved the parties’ stipulation to dismiss this derivative action without prejudice and to toll the applicable limitations period. The limitations period is tolled until fourteen days after (1) defendants provide plaintiff with a copy of the mandate issued by the Ninth Court in the securities action or (2) either party provides written notice of termination of the tolling period, whichever is first.

A second derivative action purporting to be on behalf of Harmonic was filed in the Superior Court for the County of Santa Clara on May 15, 2003. It alleges facts similar to those previously alleged in the securities class action and the federal derivative action. The complaint names as defendants former and current Harmonic officers and directors, along with former officers and directors of C-Cube Microsystems, Inc., who were named in the securities class action. The complaint also names Harmonic as a nominal defendant. The complaint alleges claims for abuse of control, gross mismanagement, and waste of corporate assets against the Harmonic defendants, and claims for breach of fiduciary duty, unjust enrichment, and negligent misrepresentation against all defendants. On July 22, 2003, the Court approved the parties’ stipulation to stay the case pending resolution of the appeal in the securities class action. Although the parties initially agreed in principle to a dismissal without prejudice on similar terms as in the federal derivative action, after further discussion, the parties decided that the stay currently in place suffices to protect their respective interests.

Based on its review of the complaints filed in the securities class action, Harmonic believes that it has meritorious defenses and intends to defend itself vigorously. There can be no assurance, however, that Harmonic will prevail. No estimate can be made of the possible range of loss associated with the resolution of this contingency and accordingly, Harmonic has not recorded a liability. An unfavorable outcome of this litigation could have a material adverse effect on Harmonic’s business, operating results, financial position or cash flows.

The Terrorist Attacks Of 2001 And The Ongoing Threat Of Terrorism Have Created Great Uncertainty And May Continue To Harm Our Business.

Current conditions in the U.S. and global economies are uncertain. The terrorist attacks in 2001 created many economic and political uncertainties that have severely impacted the global economy. We experienced a further decline in demand for our products after the attacks. The long-term effects of the attacks, the situation in Iraq and the ongoing war on terrorism on our business and on the global economy remain unknown. Moreover, the potential for future terrorist attacks has created additional uncertainty and makes it difficult to estimate how quickly the U.S. and other economies will recover and our business will improve.

Our Stock Price May Be Volatile.

The market price of our common stock has fluctuated significantly in the past, particularly in recent years, and is likely to fluctuate in the future. In addition, the securities markets have experienced significant price and volume fluctuations and the market prices of the securities of technology companies have been especially volatile. Investors may be unable to resell their shares of our common stock at or above their purchase price. In the past, companies that have experienced volatility in the market price of their stock have been the object of securities class action litigation.

We Rely On A Continuous Power Supply To Conduct Our Operations, And Any Electrical And Natural Gas Crisis Could Disrupt Our Operations And Increase Our Expenses.

We rely on a continuous power supply for manufacturing and to conduct our business operations. Interruptions in electrical power supplies in California in the early part of 2001 could recur in the future. In addition, the cost of electricity and natural gas has risen significantly. Power outages could disrupt our manufacturing and business operations and those of many of our suppliers, and could cause us to fail to meet production schedules and commitments to customers and other third parties. Any disruption to our operations or those of our suppliers could result in damage to our current and prospective business relationships and could result in lost revenue and additional expenses, thereby harming our business and operating results.

Some Anti-Takeover Provisions Contained In Our Certificate Of Incorporation, Bylaws And Stockholder Rights Plan, As Well As Provisions Of Delaware Law, Could Impair A Takeover Attempt.

Harmonic has provisions in its certificate of incorporation and bylaws, each of which could have the effect of rendering more difficult or discouraging an acquisition deemed undesirable by the Harmonic Board of Directors. These include provisions:

•		authorizing blank check preferred stock, which could be issued with voting, liquidation, dividend and other rights superior to Harmonic common stock;
•		limiting the liability of, and providing indemnification to, directors and officers;
•		limiting the ability of Harmonic stockholders to call and bring business before special meetings;
•		requiring advance notice of stockholder proposals for business to be conducted at meetings of Harmonic stockholders and for nominations of candidates for election to the Harmonic Board of Directors;
•		controlling the procedures for conduct and scheduling of Board and stockholder meetings; and
•		providing the board of directors with the express power to postpone previously scheduled annual meetings and to cancel previously scheduled special meetings.

These provisions, alone or together, could delay hostile takeovers and changes in control or management of Harmonic.

In addition, Harmonic has adopted a stockholder rights plan. The rights are not intended to prevent a takeover of Harmonic, and we believe these rights will help Harmonic’s negotiations with any potential acquirers. However, if the Board of Directors believes that a particular acquisition is undesirable, the rights may have the effect of rendering more difficult or discouraging that acquisition. The rights would cause substantial dilution to a person or group that attempts to acquire Harmonic on terms or in a manner not approved by the Harmonic Board of Directors, except pursuant to an offer conditioned upon redemption of the rights.

As a Delaware corporation, Harmonic also is subject to provisions of Delaware law, including Section 203 of the Delaware General Corporation law, which prevents some stockholders holding more than 15% of our outstanding common stock from engaging in certain business combinations without approval of the holders of substantially all of our outstanding common stock.

32

Any provision of our certificate of incorporation or bylaws, our stockholder rights plan or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for Harmonic stockholders to receive a premium for their shares of Harmonic common stock, and could also affect the price that some investors are willing to pay for Harmonic common stock.

We Have Broad Discretion In How We Use The Net Proceeds Of Our Recent Offering, And We May Not Use These Proceeds In A Manner Desired By Our Stockholders.

Our management has broad discretion with respect to the use of the net proceeds from our recent offering and investors will be relying on the judgment of our management regarding the application of these proceeds. Our management could spend most of the net proceeds from this offering in ways that our stockholders may not desire or that do not yield a favorable return. Investors will not have the opportunity, as part of your investment in our common stock, to influence the manner in which the net proceeds of this offering are used. The net proceeds from the offering are being used for general corporate purposes, including payment of existing liabilities, research and development, the development or acquisition of new products or technologies, equipment acquisitions, general working capital and operating expenses. Our financial performance may differ form our current expectations or our business needs may change as our business and the industry we address evolve. As a result, the proceeds we received in this offering may be used in a manner significantly different from our current expectations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of loss that may impact the operating results, financial position or liquidity of Harmonic due to adverse changes in market prices and rates. Harmonic is exposed to market risk because of changes in interest rates and foreign currency exchange rates as measured against the U.S. Dollar and currencies of Harmonic’s subsidiaries.

Foreign Currency Exchange Risk

Harmonic has a number of international subsidiaries each of whose sales and results of operations are generally denominated in U.S. dollars. Sales denominated in foreign currencies were approximately 7% and 4% of total net sales in the first quarter of 2004 and the full year of 2003, respectively. In addition, the Company has various international branch offices, which provide sales support and systems integration services. While Harmonic does not anticipate that near-term changes in exchange rates will have a material impact on future operating results, financial position and cash flows, Harmonic cannot assure you that a sudden and significant change in the value of local currencies would not harm Harmonic’s operating results, financial position or cash flows.

Interest Rate Risk

Exposure to market risk for changes in interest rates relate primarily to Harmonic’s investment portfolio of marketable debt securities of various issuers, types and maturities, and to Harmonic’s borrowings under its bank line of credit facility. Harmonic does not use derivative instruments in its investment portfolio, and its investment portfolio only includes highly liquid instruments with an original maturity of less than two years. These investments are classified as available for sale and are carried at estimated fair value, with material unrealized gains and losses reported in other comprehensive income. There is risk that losses could be incurred if the Company were to sell any of its securities prior to stated maturity. A 10% change in interest rates would not have a material impact on financial conditions, results of operations or cash flows.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures.

Our chief executive officer and our chief financial officer participated in the evaluation of the effectiveness of the Company’s “disclosure controls and procedures” (as defined in the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Rules 13a-15(e) or 15d-15(e)) as of the end of the period covered by this quarterly report, and

33

have concluded that our disclosure controls and procedures are effective based on their evaluation of these controls and procedures required by paragraph (b) of Exchange Act Rules 13a-15 or 15d-15.

Changes in internal controls.

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Shareholder Litigation

Between June 28 and August 25, 2000, several actions alleging violations of the federal securities laws by Harmonic and certain of its officers and directors (some of whom are no longer with Harmonic) were filed in or removed to the United States District Court for the Northern District of California. The actions subsequently were consolidated.

A consolidated complaint, filed on December 7, 2000, was brought on behalf of a purported class of persons who purchased Harmonic’s publicly traded securities between January 19 and June 26, 2000. The complaint also alleged claims on behalf of a purported subclass of persons who purchased C-Cube securities between January 19 and May 3, 2000. In addition to Harmonic and certain of its officers and directors, the complaint also named C-Cube Microsystems Inc. and several of its officers and directors as defendants. The complaint alleged that, by making false or misleading statements regarding Harmonic’s prospects and customers and its acquisition of C-Cube, certain defendants violated sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The complaint also alleged that certain defendants violated section 14(a) of the Exchange Act and sections 11, 12(a)(2), and 15 of the Securities Act of 1933 by filing a false or misleading registration statement, prospectus, and joint proxy in connection with the C-Cube acquisition.

On July 3, 2001, the Court dismissed the consolidated complaint with leave to amend. An amended complaint alleging the same claims against the same defendants was filed on August 13, 2001.

A second derivative action purporting to be on behalf of Harmonic was filed in the Superior Court for the County of Santa Clara on May 15, 2003. It alleges facts similar to those previously alleged in the securities class action and the federal derivative action. The complaint names as defendants former and current Harmonic officers and directors, along with former officers and directors of C-Cube Microsystems, Inc., who were named in the securities class action. The complaint also names Harmonic as a nominal defendant. The complaint alleges claims for abuse of control, gross mismanagement, and waste of corporate assets against the Harmonic defendants, and claims for breach of fiduciary duty, unjust enrichment, and negligent misrepresentation against all defendants.

Based on its review of the complaints filed in the securities class action, Harmonic believes that it has meritorious defenses and intends to defend itself vigorously. There can be no assurance, however, that Harmonic will prevail. No estimate can be made of the possible range of loss associated with the resolution of this contingency and accordingly, Harmonic has not recorded a liability. An unfavorable outcome of this litigation could have a material adverse effect on Harmonic’s business, operating results, financial position or cash flows.

Other Litigation

On July 3, 2003, Stanford University and Litton Systems filed a complaint in U.S. District Court for the Central District of California alleging that optical fiber amplifiers incorporated into certain of Harmonic’s products infringe U.S. Patent No. 4,859,016. This patent expired in September 2003. The complaint seeks injunctive relief, royalties and damages. Harmonic has not been served in the case. Harmonic is currently evaluating its position with respect to this patent and has engaged in discussions with the plaintiff regarding potential settlement of the matter. At this time, we are unable to determine whether we will be able to settle this litigation on reasonable terms or at all, nor can we predict the impact of an adverse outcome of this litigation if we elect to defend against it. No estimate can be made of the possible range of loss associated with the resolution of this contingency and accordingly, we have not recorded a liability associated with the outcome of a negotiated settlement or an unfavorable verdict in litigation. An unfavorable outcome of this matter could have a material adverse effect on Harmonic’s business, operating results, financial position or cash flows.
