Any division of a limited liability company shall constitute a separate Person hereunder (and each division of any limited liability company that is a Subsidiary, joint venture or any other like term shall also constitute such a Person or entity). 1.03 Accounting Terms. (a) Generally. All accounting terms not specifically or completely defined herein shall be construed in conformity with, and all financial data (including financial ratios and other financial calculations) required to be submitted pursuant to this Agreement shall be prepared in conformity with, GAAP applied on a consistent basis, as in effect from time to time, applied in a manner consistent, generally and in all material respects, with that used in preparing the Audited Financial Statements, except as otherwise specifically prescribed herein. Notwithstanding the foregoing, (a) for purposes of determining compliance with any covenant (including the computation of any financial covenant) contained herein, Indebtedness of the Company and its Subsidiaries shall be deemed to be carried at 100% of the outstanding principal amount thereof, and the effects of FASB ASC 825 and FASB ASC 470–20 on financial liabilities shall be disregarded, and (b) any obligations of a Person that are or would have been treated as operating leases for purposes of GAAP prior to the implementation of Financial Accounting Standards Board ASU No. 2016-02, Leases (Topic 842) and any interpretations thereof (“ASU 842”) shall continue to be accounted for as operating leases for purposes of all financial definitions, calculations and covenants for purpose of this Agreement (other than for purposes of the delivery of financial statements prepared in accordance with GAAP), notwithstanding the fact that such obligations are required in accordance with ASU 842 to be treated as capitalized lease or finance lease obligations in accordance with GAAP. (b) Changes in GAAP. If at any time any change in GAAP (or in the application thereof) would affect the computation of any financial ratio or requirement set forth in any Loan

42 [Harmonic] Credit Agreement #231730035 Document, and either the Company or the Required Lenders shall so request, the Administrative Agent, the Lenders and the Company shall negotiate in good faith to amend such ratio or requirement to preserve the original intent thereof in light of such change in GAAP (or in the application thereof) (subject to the approval of the Required Lenders); provided that, until so amended, (i) such ratio or requirement shall continue to be computed in accordance with GAAP prior to such change therein (or in the application thereof) and (ii) the Company shall provide to the Administrative Agent and the Lenders financial statements and other documents required under this Agreement or as reasonably requested hereunder setting forth a reconciliation between calculations of such ratio or requirement made before and after giving effect to such change in GAAP (or in the application thereof). (c) Consolidation of Variable Interest Entities. All references herein to Consolidated financial statements of Company and its Subsidiaries or to the determination of any amount for Company and its Subsidiaries on a Consolidated basis or any similar reference shall, in each case, be deemed to include each variable interest entity that Company is required to consolidate pursuant to FASB ASC 810 as if such variable interest entity were a Subsidiary as defined herein. (d) Pro Forma Treatment. Each Disposition of all or substantially all of a line of business, and each Acquisition, by the Company and its Subsidiaries that is consummated during any Measurement Period shall, for purposes of determining compliance with the financial covenants set forth in Section 7.11 and for purposes of determining the Applicable Rate, be given Pro Forma Effect as of the first day of such Measurement Period. (e) For purposes of determining the permissibility of any action, change, transaction, or other event (each of the foregoing, a “Proposed Event”) that requires a calculation of any financial ratio or test (including, without limitation, Section 7.11, any Consolidated Leverage Ratio test, any Consolidated Fixed Charge Coverage Ratio test, and/or the amount of Consolidated EBITDA), such financial ratio or test shall be calculated at the time such action is taken (subject to Section 1.09), such change is made, such transaction is consummated or such event occurs, as the case may be (any such time, the “Reference Time”). No Default or Event of Default shall be deemed to have occurred as a result of the Proposed Event having occurred notwithstanding the fact that a change in such financial ratio or test occurred after the applicable Reference Time which would have otherwise made the Proposed Event impermissible hereunder. 1.04 Rounding. Any financial ratios required to be maintained by the Borrower pursuant to this Agreement shall be calculated by dividing the appropriate component by the other component, carrying the result to one place more than the number of places by which such ratio is expressed herein and rounding the result up or down to the nearest number (with a rounding-up if there is no nearest number). 1.05 Times of Day. Unless otherwise specified, all references herein to times of day shall be references to Eastern time (daylight or standard, as applicable). 1.06 Letter of Credit Amounts. Unless otherwise specified herein, the amount of a Letter of Credit at any time shall be deemed to be the stated amount of such Letter of Credit in effect at such time; provided that with respect to any Letter of Credit that, by its terms or the terms of any Issuer Document related thereto, provides for one or more

43 [Harmonic] Credit Agreement #231730035 automatic increases in the stated amount thereof, the amount of such Letter of Credit shall be deemed to be the maximum stated amount of such Letter of Credit after giving effect to all such increases, whether or not such maximum stated amount is in effect at such time. 1.07 Interest Rates. The Administrative Agent does not warrant, nor accept responsibility, nor shall the Administrative Agent have any liability with respect to the administration, submission or any other matter related to any reference rate referred to herein or with respect to any rate (including, for the avoidance of doubt, the selection of such rate and any related spread or other adjustment) that is an alternative or replacement for or successor to any such rate (including, without limitation, any Successor Rate) (or any component of any of the foregoing) or the effect of any of the foregoing, or of any Conforming Changes. The Administrative Agent and its affiliates or other related entities may engage in transactions or other activities that affect any reference rate referred to herein, or any alternative, successor or replacement rate (including, without limitation, any Successor Rate) (or any component of any of the foregoing) or any related spread or other adjustments thereto, in each case, in a manner adverse to the Borrower. The Administrative Agent may select information sources or services in its reasonable discretion to ascertain any reference rate referred to herein or any alternative, successor or replacement rate (including, without limitation, any Successor Rate) (or any component of any of the foregoing), in each case pursuant to the terms of this Agreement, and shall have no liability to the Borrower, any Lender or any other person or entity for damages of any kind, including direct or indirect, special, punitive, incidental or consequential damages, costs, losses or expenses (whether in tort, contract or otherwise and whether at law or in equity), for any error or other action or omission related to or affecting the selection, determination, or calculation of any rate (or component thereof) provided by any such information source or service. 1.08 UCC Terms. Terms defined in the UCC in effect on the Closing Date and not otherwise defined herein shall, unless the context otherwise indicates, have the meanings provided by those definitions. Subject to the foregoing, the term “UCC” refers, as of any date of determination, to the UCC then in effect. 1.09 Limited Condition Acquisitions. In the event that the Company notifies the Administrative Agent in writing that any proposed Acquisition is a Limited Condition Acquisition and that the Company wishes to test the conditions to such Acquisition and the Indebtedness that is to be used to finance such Acquisition in accordance with this Section 1.09 (but subject, if applicable, to Section 2.16), then the following provisions shall apply: (a) any condition to such Limited Condition Acquisition or such Indebtedness that requires that no Default shall have occurred and be continuing at the time of such Limited Condition Acquisition or the incurrence of such Indebtedness, shall be satisfied if (i) no Default shall have occurred and be continuing at the time of the execution of the definitive purchase agreement, merger agreement or other acquisition agreement governing such Limited Condition Acquisition (the “LCA Test Date”) and (ii) no Default under any of Section 8.01(a) or 8.01(f) shall have occurred and be continuing both immediately before and immediately after giving effect to such Limited Condition Acquisition and any Indebtedness incurred in connection therewith (including any such additional Indebtedness); (b) any condition to such Limited Condition Acquisition or such Indebtedness that the representations and warranties in this Agreement and the other Loan Documents shall be true and correct at the time of consummation of such Limited Condition Acquisition or the incurrence of such Indebtedness shall be deemed satisfied if (i) all representations and warranties in this Agreement and the other Loan

44 [Harmonic] Credit Agreement #231730035 Documents are true and correct in all material respects (except for any representation and warranty that is qualified by materiality or reference to Material Adverse Effect, which such representation and warranty shall be true and correct in all respects) as of the LCA Test Date, or if such representation speaks as of an earlier date, as of such earlier date and (ii) as of the date of consummation of such Limited Condition Acquisition, (A) the representations and warranties under the relevant definitive agreement governing such Limited Condition Acquisition as are material to the lenders providing such Indebtedness shall be true and correct, but only to the extent that the Company or its applicable Subsidiary has the right to terminate its obligations under such agreement or otherwise decline to close such Limited Condition Acquisition as a result of a breach of such representations and warranties or the failure of those representations and warranties to be true and correct and (B) certain of the representations and warranties in this Agreement and the other Loan Documents which are customary for similar “funds certain” financings and required by the lenders providing such Indebtedness shall be true and correct in all material respects (except for any representation and warranty that is qualified by materiality or reference to Material Adverse Effect, which such representation and warranty shall be true and correct in all respects); (c) any financial ratio test or condition to be tested in connection with such Limited Condition Acquisition and the availability of such Indebtedness will be tested as of the LCA Test Date, in each case, after giving effect to the relevant Limited Condition Acquisition and related incurrence of Indebtedness, on a Pro Forma Basis where applicable, and, for the avoidance of doubt, (i) such ratios and baskets shall not be tested at the time of consummation of such Limited Condition Acquisition and (ii) if any of such ratios are exceeded or conditions are not met following the LCA Test Date, but prior to the closing of such Limited Condition Acquisition, as a result of fluctuations in such ratio or amount (including due to fluctuations in Consolidated EBITDA of the Company or the Person subject to such Limited Condition Acquisition), at or prior to the consummation of the relevant transaction or action, such ratios will not be deemed to have been exceeded and such conditions will not be deemed unmet as a result of such fluctuations solely for purposes of determining whether the relevant transaction or action is permitted to be consummated or taken; (d) except as provided in the next sentence, in connection with any subsequent calculation of any ratio or basket on or following the relevant LCA Test Date and prior to the earlier of the date on which such Limited Condition Acquisition is consummated and the date that the definitive agreement for such Limited Condition Acquisition is terminated or expires without consummation of such Limited Condition Acquisition, any such ratio or basket shall be calculated (i) on a Pro Forma Basis assuming such Limited Condition Acquisition and other transactions in connection therewith (including the incurrence or assumption of Indebtedness) have been consummated and (ii) assuming such Limited Condition Acquisition and other transactions in connection therewith (including the incurrence or assumption of Indebtedness) have not been consummated. Notwithstanding the foregoing, any calculation of a ratio in connection with determining the Applicable Rate and determining whether or not the Company is in compliance with the financial covenants set forth in Section 7.11 shall, in each case be calculated assuming such Limited Condition Acquisition and other transactions in connection therewith (including the incurrence or assumption of Indebtedness) have not been consummated. The foregoing provisions shall apply with similar effect during the pendency of multiple Limited Condition Acquisitions such that each of the possible scenarios is separately tested.

45 [Harmonic] Credit Agreement #231730035 ARTICLE II COMMITMENTS AND CREDIT EXTENSIONS 2.01 Loans. (a) Term Borrowing. Subject to the terms and conditions set forth herein, each Term Lender severally agrees to make up to three (3) term loans to the Borrower, in Dollars, from time to time, on any Business Day during the Availability Period for the Term Facility, in an aggregate amount not to exceed such Term Lender’s Applicable Percentage of the Term Facility. Each Term Borrowing shall consist of Term Loans made simultaneously by the Term Lenders in accordance with their respective Applicable Percentage of the Term Facility. Term Borrowings repaid or prepaid may not be reborrowed. Term Loans may be Base Rate Loans or Term SOFR Loans, as further provided herein. (b) Revolving Borrowings. Subject to the terms and conditions set forth herein, each Revolving Lender severally agrees to make loans (each such loan, a “Revolving Loan”) to the Borrower, in Dollars, from time to time, on any Business Day during the Availability Period for the Revolving Facility, in an aggregate amount not to exceed at any time outstanding the amount of such Lender’s Revolving Commitment; provided that after giving effect to any Revolving Borrowing, (i) the Total Revolving Outstandings shall not exceed the Revolving Facility, and (ii) the Revolving Exposure of any Lender shall not exceed such Revolving Lender’s Revolving Commitment. Within the limits of each Revolving Lender’s Revolving Commitment, and subject to the other terms and conditions hereof, the Borrower may borrow Revolving Loans, prepay under Section 2.05, and reborrow under this Section 2.01. Revolving Loans may be Base Rate Loans or Term SOFR Loans, as further provided herein. 2.02 Borrowings, Conversions and Continuations of Loans. (a) Notice of Borrowing. Each Borrowing, each conversion of Loans from one Type to the other, and each continuation of Term SOFR Loans shall be made upon the Borrower’s irrevocable notice to the Administrative Agent, which may be given by (A) telephone or (B) a Loan Notice; provided that any telephonic notice must be confirmed immediately by delivery to the Administrative Agent of a Loan Notice. Each such Loan Notice must be received by the Administrative Agent not later than 12:00 p.m. (i) three Business Days prior to the requested date of any Borrowing of, conversion to or continuation of Term SOFR Loans or of any conversion of Term SOFR Loans to Base Rate Loans, and (ii) on the requested date of any Borrowing of Base Rate Loans. Each Borrowing of, conversion to or continuation of Term SOFR Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof (or, in connection with any conversion or continuation of a Term Loan, if less, the entire principal thereof then outstanding). Except as provided in Sections 2.03(f) and 2.04(c), each Borrowing of or conversion to Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof (or, in connection with any conversion or continuation of a Term Loan, if less, the entire principal thereof then outstanding). Each Loan Notice shall specify (i) the applicable Facility and whether the Borrower is requesting a Borrowing, a conversion of Loans from one Type to the other, or a continuation of Loans, as the case may be, under such Facility, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal amount of Loans to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or to which existing Loans are to be converted, (v) if applicable, the duration of the Interest Period with respect thereto and (vi) if applicable, the Designated Borrower. If the Borrower fails to specify a Type of Loan in a Loan Notice or if the

46 [Harmonic] Credit Agreement #231730035 Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Loans shall be made as, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Term SOFR Loans. If the Borrower requests a Borrowing of, conversion to, or continuation of Term SOFR Loans in any such Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month. Notwithstanding anything to the contrary herein, a Swingline Loan may not be converted to a Term SOFR Loan. (b) Advances. Following receipt of a Loan Notice for the Facility, the Administrative Agent shall promptly notify each Appropriate Lender of the amount of its Applicable Percentage under such Facility of the applicable Loans, and if no timely notice of a conversion or continuation is provided by the Borrower, the Administrative Agent shall notify each Lender of the details of any automatic conversion to Base Rate Loans described in Section 2.02(a). In the case of a Borrowing, each Appropriate Lender shall make the amount of its Loan available to the Administrative Agent in immediately available funds at the Administrative Agent’s Office not later than 1:00 p.m. on the Business Day specified in the applicable Loan Notice. Upon satisfaction of the applicable conditions set forth in Section 4.02 (and, if such Borrowing is the initial Credit Extension, Section 4.01), the Administrative Agent shall make all funds so received available to the Borrower in like funds as received by the Administrative Agent either by (i) crediting the account of the Borrower on the books of Citibank with the amount of such funds or (ii) wire transfer of such funds, in each case in accordance with instructions provided to (and reasonably acceptable to) the Administrative Agent by the Borrower; provided that if, on the date the Loan Notice with respect to a Revolving Borrowing is given by the Borrower, there are L/C Borrowings outstanding, then the proceeds of a Revolving Borrowing, first, shall be applied to the payment in full of any such L/C Borrowings, and second, shall be made available to the Borrower as provided above. (c) Term SOFR Loans. Except as otherwise provided herein, a Term SOFR Loan may be continued or converted only on the last day of an Interest Period for such Term SOFR Loan. During the existence of a Default, no Loans may be requested as, converted to or continued as Term SOFR Loans without the consent of the Required Lenders, and the Required Lenders may demand that any or all of the outstanding Term SOFR Loans be converted immediately to Base Rate Loans. (d) Interest Rates. Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. (e) Interest Periods. After giving effect to all Term Borrowings, all conversions of Term Loans from one Type to the other, and all continuations of Term Loans as the same Type, there shall not be more than eight (8) Interest Periods in effect in respect of the Term Facility. After giving effect to all Revolving Borrowings, all conversions of Revolving Loans from one Type to the other, and all continuations of Revolving Loans as the same Type, there shall not be more than eight (8) Interest Periods in effect in respect of the Revolving Facility. (f) Cashless Settlement Mechanism. Notwithstanding anything to the contrary in this Agreement, any Lender may exchange, continue or rollover all or the portion of its Loans in connection with any refinancing, extension, loan modification or similar transaction permitted by the terms of this Agreement, pursuant to a cashless settlement mechanism approved by the Borrower, the Administrative Agent, and such Lender. (g) Conforming Changes. With respect to SOFR or Term SOFR, the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding

47 [Harmonic] Credit Agreement #231730035 anything to the contrary herein or in any other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document; provided that, with respect to any such amendment effected, the Administrative Agent shall post each such amendment implementing such Conforming Changes to the Borrower and the Lenders reasonably promptly after such amendment becomes effective. 2.03 Letters of Credit. (a) The Letter of Credit Commitment. Subject to the terms and conditions set forth herein, in addition to the Loans provided for in Section 2.01, the Borrower may request that the L/C Issuer, in reliance on the agreements of the Revolving Lenders set forth in this Section 2.03, issue, at any time and from time to time during the Availability Period, Letters of Credit denominated in Dollars for its own account or the account of any of its Domestic Subsidiaries in such form as is acceptable to the Administrative Agent and the L/C Issuer in its reasonable determination. Letters of Credit issued hereunder shall constitute utilization of the Revolving Commitments. (b) Notice of Issuance, Amendment, Extension, Reinstatement or Renewal. (i) To request the issuance of a Letter of Credit (or the amendment of the terms and conditions, extension of the terms and conditions, extension of the expiration date, or reinstatement of amounts paid, or renewal of an outstanding Letter of Credit), the Borrower shall deliver (or transmit by electronic communication, if arrangements for doing so have been approved by the L/C Issuer) to the L/C Issuer selected by it and to the Administrative Agent not later than 12:00 p.m. at least two (2) Business Days (or such later date and time as the Administrative Agent and the L/C Issuer may agree in a particular instance in their sole discretion) prior to the proposed issuance date or date of amendment, as the case may be a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, extended, reinstated or renewed, and specifying the date of issuance, amendment, extension, reinstatement or renewal (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with clause (d) of this Section 2.03), the amount of such Letter of Credit, the name and address of the beneficiary thereof, the purpose and nature of the requested Letter of Credit and such other information as shall be necessary to prepare, amend, extend, reinstate or renew such Letter of Credit. If requested by the L/C Issuer, the Borrower also shall submit a letter of credit application and reimbursement agreement on the L/C Issuer’s standard form in connection with any request for a Letter of Credit. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application and reimbursement agreement or other agreement submitted by the Borrower to, or entered into by the Borrower with, the L/C Issuer relating to any Letter of Credit, the terms and conditions of this Agreement shall control. (c) Limitations on Amounts, Issuance and Amendment. A Letter of Credit shall be issued, amended, extended, reinstated or renewed only if (and upon issuance, amendment, extension, reinstatement or renewal of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, extension, reinstatement or renewal (w) the aggregate amount of the outstanding Letters of Credit issued by the L/C Issuer shall not exceed its L/C Commitment, (x) the aggregate L/C Obligations shall not exceed the L/C Sublimit, (y) the Revolving Exposure of any Lender shall not exceed its Revolving

48 [Harmonic] Credit Agreement #231730035 Commitment and (z) the Total Revolving Exposure shall not exceed the total Revolving Commitments. (i) The L/C Issuer shall not be under any obligation to issue any Letter of Credit if: (A) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the L/C Issuer from issuing the Letter of Credit, or any Law applicable to the L/C Issuer or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the L/C Issuer shall prohibit, or request that the L/C Issuer refrain from, the issuance of letters of credit generally or the Letter of Credit in particular or shall impose upon the L/C Issuer with respect to the Letter of Credit any restriction, reserve or capital requirement (for which the L/C Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon the L/C Issuer any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which the L/C Issuer in good faith deems material to it; (B) the issuance of such Letter of Credit would violate one or more policies of the L/C Issuer applicable to letters of credit generally; (C) except as otherwise agreed by the Administrative Agent and the L/C Issuer, the Letter of Credit is in an initial stated amount less than $500,000; (D) any Revolving Lender is at that time a Defaulting Lender, unless the L/C Issuer has entered into arrangements, including the delivery of Cash Collateral, satisfactory to the L/C Issuer (in its sole discretion) with the Borrower or such Lender to eliminate the L/C Issuer’s actual or potential Fronting Exposure (after giving effect to Section 2.15(a)(iv)) with respect to the Defaulting Lender arising from either the Letter of Credit then proposed to be issued or that Letter of Credit and all other L/C Obligations as to which the L/C Issuer has actual or potential Fronting Exposure, as it may elect in its sole discretion; or (E) the Letter of Credit contains any provisions for automatic reinstatement of the stated amount after any drawing thereunder. (ii) The L/C Issuer shall be under no obligation to amend any Letter of Credit if (A) the L/C Issuer would have no obligation at such time to issue the Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of the Letter of Credit does not accept the proposed amendment to the Letter of Credit. (d) Expiration Date. Each Letter of Credit shall have a stated expiration date no later than the earlier of (ix) the date twelve (12) months after the date of the issuance of such Letter of Credit (or, in the case of any extension of the expiration date thereof, whether automatic or by amendment, twelve months after the then-current expiration date of such Letter of Credit) and (x) the date that is five (5) Business Days prior to the Maturity Date. (e) Participations.

49 [Harmonic] Credit Agreement #231730035 (i) By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount or extending the expiration date thereof), and without any further action on the part of the L/C Issuer or the Lenders, the L/C Issuer hereby grants to each Revolving Lender, and each Revolving Lender hereby acquires from the L/C Issuer, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. Each Revolving Lender acknowledges and agrees that its obligation to acquire participations pursuant to this clause (e) in respect of Letters of Credit is absolute, unconditional and irrevocable and shall not be affected by any circumstance whatsoever, including any amendment, extension, reinstatement or renewal of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Revolving Commitments. (ii) In consideration and in furtherance of the foregoing, each Revolving Lender hereby absolutely, unconditionally and irrevocably agrees to pay to the Administrative Agent, for account of the L/C Issuer, such Lender’s Applicable Percentage of each L/C Disbursement made by the L/C Issuer not later than 1:00 p.m. on the Business Day specified in the notice provided by the Administrative Agent to the Revolving Lenders pursuant to Section 2.03(f) until such L/C Disbursement is reimbursed by the Borrower or at any time after any reimbursement payment is required to be refunded to the Borrower for any reason, including after the Maturity Date. Such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each such payment shall be made in the same manner as provided in Section 2.02 with respect to Loans made by such Lender (and Section 2.02 shall apply, mutatis mutandis, to the payment obligations of the Revolving Lenders pursuant to this Section 2.03), and the Administrative Agent shall promptly pay to the L/C Issuer the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to Section 2.03(f), the Administrative Agent shall distribute such payment to the L/C Issuer or, to the extent that the Revolving Lenders have made payments pursuant to this clause (e) to reimburse the L/C Issuer, then to such Lenders and the L/C Issuer as their interests may appear. Any payment made by a Lender pursuant to this clause (e) to reimburse the L/C Issuer for any L/C Disbursement shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such L/C Disbursement. (iii) Each Revolving Lender further acknowledges and agrees that its participation in each Letter of Credit will be automatically adjusted to reflect such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit at each time such Lender’s Commitment is amended pursuant to the operation of Section 2.16, as a result of an assignment in accordance with Section 11.06 or otherwise pursuant to this Agreement. (iv) If any Revolving Lender fails to make available to the Administrative Agent for the account of the L/C Issuer any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.03(e), then, without limiting the other provisions of this Agreement, the L/C Issuer shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the L/C Issuer at a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by the L/C Issuer in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the L/C Issuer in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute

50 [Harmonic] Credit Agreement #231730035 such Lender’s Revolving Loan included in the relevant Revolving Borrowing or L/C Advance in respect of the relevant L/C Borrowing, as the case may be. A certificate of the L/C Issuer submitted to any Revolving Lender (through the Administrative Agent) with respect to any amounts owing under this clause (e)(iv) shall be conclusive absent manifest error. (f) Reimbursement. If the L/C Issuer shall make any L/C Disbursement in respect of a Letter of Credit, the Borrower shall reimburse the L/C Issuer in respect of such L/C Disbursement by paying to the Administrative Agent an amount equal to such L/C Disbursement not later than 1:00 p.m. on (i) the Business Day that the Borrower receives notice of such L/C Disbursement, if such notice is received prior to 10:00 a.m. or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time, provided that, if such L/C Disbursement is not less than $1,000,000, the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.02 or Section 2.04 that such payment be financed with a Borrowing of a Base Rate Loan or a Swingline Loan in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Borrowing of Base Rate Loans or Swingline Loan. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Revolving Lender of the applicable L/C Disbursement, the payment then due from the Borrower in respect thereof (the “Unreimbursed Amount”) and such Lender’s Applicable Percentage thereof. Promptly upon receipt of such notice, each Revolving Lender shall pay to the Administrative Agent its Applicable Percentage of the Unreimbursed Amount pursuant to Section 2.03(e)(ii), subject to the amount of the unutilized portion of the aggregate Revolving Commitments. Any notice given by the L/C Issuer or the Administrative Agent pursuant to this Section 2.03(f) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice. (g) Obligations Absolute. The Borrower’s obligation to reimburse L/C Disbursements as provided in clause (f) of this Section 2.03 shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of: (i) any lack of validity or enforceability of this Agreement, any other Loan Document or any Letter of Credit, or any term or provision herein or therein; (ii) the existence of any claim, counterclaim, setoff, defense or other right that the Borrower or any Subsidiary may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the L/C Issuer or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction; (iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement in such draft or other document being untrue or inaccurate in any respect; (iv) waiver by the L/C Issuer of any requirement that exists for the L/C Issuer’s protection and not the protection of the Borrower or any waiver by the L/C Issuer which does not in fact materially prejudice the Borrower;

51 [Harmonic] Credit Agreement #231730035 (v) honor of a demand for payment presented electronically even if such Letter of Credit required that demand be in the form of a draft; (vi) any payment made by the L/C Issuer in respect of an otherwise complying item presented after the date specified as the expiration date of, or the date by which documents must be received under such Letter of Credit if presentation after such date is authorized by the UCC or the ISP, as applicable; (vii) payment by the L/C Issuer under a Letter of Credit against presentation of a draft or other document that does not comply strictly with the terms of such Letter of Credit; or (viii) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.03, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. (h) Examination. The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will immediately notify the L/C Issuer. The Borrower shall be conclusively deemed to have waived any such claim against the L/C Issuer and its correspondents unless such notice is given as aforesaid. (i) Liability. None of the Administrative Agent, the Lenders, the L/C Issuer, or any of their Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit by the L/C Issuer or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms, any error in translation or any consequence arising from causes beyond the control of the L/C Issuer; provided that the foregoing shall not be construed to excuse the L/C Issuer from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by Applicable Law) suffered by the Borrower that are caused by the L/C Issuer’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the L/C Issuer (as finally determined by a court of competent jurisdiction), the L/C Issuer shall be deemed to have exercised care in each such determination, and that: (i) the L/C Issuer may replace a purportedly lost, stolen, or destroyed original Letter of Credit or missing amendment thereto with a certified true copy marked as such or waive a requirement for its presentation; (ii) the L/C Issuer may accept documents that appear on their face to be in substantial compliance with the terms of a Letter of Credit without responsibility for further investigation, regardless of any notice or information to the contrary, and may make payment upon presentation of documents that appear on their face to be in substantial compliance with the terms of such Letter of Credit and without regard to any non- documentary condition in such Letter of Credit;

52 [Harmonic] Credit Agreement #231730035 (iii) the L/C Issuer shall have the right, in its sole discretion, to decline to accept such documents and to make such payment if such documents are not in strict compliance with the terms of such Letter of Credit; and (iv) this sentence shall establish the standard of care to be exercised by the L/C Issuer when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof (and the parties hereto hereby waive, to the extent permitted by Applicable Law, any standard of care inconsistent with the foregoing). Without limiting the foregoing, none of the Administrative Agent, the Lenders, the L/C Issuer, or any of their Related Parties shall have any liability or responsibility by reason of (A) any presentation that includes forged or fraudulent documents or that is otherwise affected by the fraudulent, bad faith, or illegal conduct of the beneficiary or other Person, (B) the L/C Issuer declining to take-up documents and make payment, (C) against documents that are fraudulent, forged, or for other reasons by which that it is entitled not to honor, (D) following a Borrower’s waiver of discrepancies with respect to such documents or request for honor of such documents or (E) the L/C Issuer retaining proceeds of a Letter of Credit based on an apparently applicable attachment order, blocking regulation, or third-party claim notified to the L/C Issuer. (j) Applicability of ISP. Unless otherwise expressly agreed by the L/C Issuer and the Borrower when a Letter of Credit is issued by it (including any such agreement applicable to an Existing Letter of Credit), the rules of the ISP shall apply to each Letter of Credit. Notwithstanding the foregoing, the L/C Issuer shall not be responsible to the Borrower for, and the L/C Issuer’s rights and remedies against the Borrower shall not be impaired by, any action or inaction of the L/C Issuer required or permitted under any law, order, or practice that is required or permitted to be applied to any Letter of Credit or this Agreement, including the Law or any order of a jurisdiction where the L/C Issuer or the beneficiary is located, the practice stated in the ISP or UCP, as applicable, or in the decisions, opinions, practice statements, or official commentary of the ICC Banking Commission, the Bankers Association for Finance and Trade – International Financial Services Association (BAFT-IFSA), or the Institute of International Banking Law & Practice, whether or not any Letter of Credit chooses such law or practice. (k) Benefits. The L/C Issuer shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith, and the L/C Issuer shall have all of the benefits and immunities (i) provided to the Administrative Agent in Article IX with respect to any acts taken or omissions suffered by the L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and Issuer Documents pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as used in Article IX included the L/C Issuer with respect to such acts or omissions, and (ii) as additionally provided herein with respect to the L/C Issuer. (l) Letter of Credit Fees. The Borrower shall pay to the Administrative Agent for the account of each Revolving Lender in accordance with its Applicable Revolving Percentage a Letter of Credit fee (the “Letter of Credit Fee”) for each Letter of Credit equal to the Applicable Rate times the daily amount available to be drawn under such Letter of Credit. For purposes of computing the daily amount available to be drawn under any standby Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.06. Letter of Credit Fees shall be (i) payable on the first Business Day following the end of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit and (ii) accrued through and including the last day of each calendar quarter in arrears. If

53 [Harmonic] Credit Agreement #231730035 there is any change in the Applicable Rate during any quarter, the daily amount available to be drawn under each Letter of Credit shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect. Notwithstanding anything to the contrary contained herein, upon the request of the Required Revolving Lenders, while any Event of Default exists, all Letter of Credit Fees shall accrue at the Default Rate. (m) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. The Borrower shall pay directly to the L/C Issuer for its own account a fronting fee with respect to each Letter of Credit, at the rate per annum equal to 0.125%, computed on the daily amount available to be drawn under such Letter of Credit on a quarterly basis in arrears. Such fronting fee shall be due and payable no later than the tenth Business Day after the end of each March, June, September and December in the most recently-ended quarterly period (or portion thereof, in the case of the first payment), commencing with the first such date to occur after the issuance of such Letter of Credit, on the Maturity Date and thereafter on demand. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.06. In addition, the Borrower shall pay directly to the L/C Issuer, for its own account, the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of the L/C Issuer relating to letters of credit as from time to time in effect. Such customary fees and standard costs and charges are due and payable on demand and are nonrefundable. (n) Disbursement Procedures. The L/C Issuer for any Letter of Credit shall, within the time allowed by Applicable Laws or the specific terms of the Letter of Credit following its receipt thereof, examine all documents purporting to represent a demand for payment under such Letter of Credit. The L/C Issuer shall promptly after such examination notify the Administrative Agent and the Borrower in writing of such demand for payment if the L/C Issuer has made or will make an L/C Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the L/C Issuer and the Lenders with respect to any such L/C Disbursement. (o) Interim Interest. If the L/C Issuer for any standby Letter of Credit shall make any L/C Disbursement, then, unless the Borrower shall reimburse such L/C Disbursement in full on the date such L/C Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such L/C Disbursement is made to but excluding the date that the Borrower reimburses such L/C Disbursement, at the rate per annum then applicable to Base Rate Loans; provided that if the Borrower fails to reimburse such L/C Disbursement when due pursuant to clause (f) of this Section 2.03, then Section 2.08(b) shall apply. Interest accrued pursuant to this clause (p) shall be for account of the L/C Issuer, except that interest accrued on and after the date of payment by any Lender pursuant to clause (f) of this Section 2.03 to reimburse the L/C Issuer shall be for account of such Lender to the extent of such payment. (p) Replacement and Resignation of the L/C Issuer. (i) The L/C Issuer may be replaced at any time by written agreement between the Borrower, the Administrative Agent, the replaced L/C Issuer and the successor L/C Issuer. The Administrative Agent shall notify the Lenders of any such replacement of the L/C Issuer. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced L/C Issuer pursuant to Section 2.03(m). From and after the effective date of any such replacement, (i) the successor L/C Issuer shall have all the rights and obligations of an L/C Issuer under this

54 [Harmonic] Credit Agreement #231730035 Agreement with respect to Letters of Credit to be issued by it thereafter and (ii) references herein to the term “L/C Issuer” shall be deemed to include such successor or any previous L/C Issuer, or such successor and all previous L/C Issuer, as the context shall require. After the replacement of the L/C Issuer hereunder, the replaced L/C Issuer shall remain a party hereto and shall continue to have all the rights and obligations of an L/C Issuer under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit. (ii) Any L/C Issuer may resign at any time by giving thirty (30) days’ prior notice to the Administrative Agent, the Lenders and the Company. After the resignation of a L/C Issuer hereunder, the retiring L/C Issuer shall remain a party hereto and shall continue to have all the rights and obligations of an L/C Issuer under this Agreement and the other Loan Documents with respect to Letters of Credit issued by it prior to such resignation, but shall not be required to issue additional Letters of Credit or to extend, renew or increase the outstanding Letter of Credit (q) Cash Collateralization. (i) If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Revolving Lenders (or, if the maturity of the Loans has been accelerated, Revolving Lenders with L/C Obligations representing at least 66-2/3% of the total L/C Obligations) demanding the deposit of Cash Collateral pursuant to this clause (q), the Borrower shall immediately deposit into an account established and maintained on the books and records of the Administrative Agent (the “Collateral Account”) an amount in cash equal to 105% of the total L/C Obligations as of such date plus any accrued and unpaid interest thereon, provided that the obligation to deposit such Cash Collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (f) of Section 8.01. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. In addition, and without limiting the foregoing or clause (d) of this Section 2.03, if any L/C Obligations remain outstanding after the expiration date specified in said clause (d), the Borrower shall immediately deposit into the Collateral Account an amount in cash equal to 105% of such L/C Obligations as of such date plus any accrued and unpaid interest thereon. (ii) The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over the Collateral Account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in the Collateral Account. Moneys in the Collateral Account shall be applied by the Administrative Agent to reimburse the L/C Issuer for L/C Disbursements for which it has not been reimbursed, together with related fees, costs, and customary processing charges, and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the L/C Obligations at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with L/C Obligations representing 66-2/3% of the total L/C Obligations), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of Cash Collateral hereunder as a result of the occurrence of an Event

55 [Harmonic] Credit Agreement #231730035 of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three (3) Business Days after all Events of Default have been cured or waived. (r) Letters of Credit Issued for Domestic Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Domestic Subsidiary, the Borrower shall be obligated to reimburse, indemnify and compensate the L/C Issuer hereunder for any and all drawings under such Letter of Credit as if such Letter of Credit had been issues solely for the account of the Borrower. The Borrower irrevocably waives any and all defenses that might otherwise be available to it as a guarantor or surety of any or all of the obligations of such Subsidiary in respect of such Letter of Credit. The Borrower hereby acknowledges that the issuance of Letters of Credit for the account of Domestic Subsidiaries inures to the benefit of the Borrower, and that the Borrower’s business derives substantial benefits from the businesses of such Subsidiaries. (s) L/C Issuer Reports to the Administrative Agent. Unless otherwise agreed by the Administrative Agent, each L/C Issuer shall, in addition to its notification obligations set forth elsewhere in this Section 2.03, provide the Administrative Agent a Letter of Credit Report, as set forth below: (i) reasonably prior to the time that such L/C Issuer issues, amends, renews, increases or extends a Letter of Credit, the date of such issuance, amendment, renewal, increase or extension and the stated amount of the applicable Letters of Credit after giving effect to such issuance, amendment, renewal or extension (and whether the amounts thereof shall have changed); (ii) on each Business Day on which such L/C Issuer makes a payment pursuant to a Letter of Credit, the date and amount of such payment; (iii) on any Business Day on which the Borrower fails to reimburse a payment made pursuant to a Letter of Credit required to be reimbursed to such L/C Issuer on such day, the date of such failure and the amount of such payment; (iv) on any other Business Day, such other information as the Administrative Agent shall reasonably request as to the Letters of Credit issued by such L/C Issuer; and (v) for so long as any Letter of Credit issued by an L/C Issuer is outstanding, such L/C Issuer shall deliver to the Administrative Agent (A) on the last Business Day of each calendar month, (B) at all other times a Letter of Credit Report is required to be delivered pursuant to this Agreement, and (C) on each date that (1) an L/C Credit Extension occurs or (2) there is any expiration, cancellation and/or disbursement, in each case, with respect to any such Letter of Credit, a Letter of Credit Report appropriately completed with the information for every outstanding Letter of Credit issued by such L/C Issuer. (t) Conflict with Issuer Documents. In the event of any conflict between the terms hereof and the terms of any Issuer Document, the terms hereof shall control. 2.04 Swingline Loans. (a) The Swingline. Subject to the terms and conditions set forth herein, the Swingline Lender, in reliance upon the agreements of the other Lenders set forth in this Section 2.04, may in

56 [Harmonic] Credit Agreement #231730035 its sole discretion make loans to the Borrower (each such loan, a “Swingline Loan”). Each such Swingline Loan may be made, subject to the terms and conditions set forth herein, to the Borrower, in Dollars, from time to time on any Business Day during the Availability Period in an aggregate amount not to exceed at any time outstanding the amount of the Swingline Sublimit; provided that (i) after giving effect to any Swingline Loan, (A) the Total Revolving Outstandings shall not exceed the Revolving Facility at such time, (B) the Revolving Exposure of any Revolving Lender at such time shall not exceed such Lender’s Revolving Commitment and (C) the aggregate amount of all Swingline Loans outstanding shall not exceed the Swingline Commitment of the Swingline Lender, (ii) the Borrower shall not use the proceeds of any Swingline Loan to refinance any outstanding Swingline Loan, and (iii) the Swingline Lender shall not be under any obligation to make any Swingline Loan if it shall determine (which determination shall be conclusive and binding absent manifest error) that it has, or by such Credit Extension may have, Fronting Exposure. Within the foregoing limits, and subject to the other terms and conditions hereof, the Borrower may borrow under this Section 2.04, prepay under Section 2.05, and reborrow under this Section 2.04. Each Swingline Loan shall bear interest only at a rate based on the Base Rate plus the Applicable Rate. Immediately upon the making of a Swingline Loan, each Revolving Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swingline Lender a risk participation in such Swingline Loan in an amount equal to the product of such Revolving Lender’s Applicable Revolving Percentage times the amount of such Swingline Loan. (b) Borrowing Procedures. Each Swingline Borrowing shall be made upon the Borrower’s irrevocable notice to the Swingline Lender and the Administrative Agent, which may be given by: (i) telephone or (ii) a Swingline Loan Notice; provided that any telephonic notice must be confirmed immediately by delivery to the Swingline Lender and the Administrative Agent of a Swingline Loan Notice. Each such Swingline Loan Notice must be received by the Swingline Lender and the Administrative Agent not later than 1:00 p.m. on the requested borrowing date, and shall specify (A) the amount to be borrowed, which shall be a minimum of $250,000, and (B) the requested date of the Borrowing (which shall be a Business Day). Promptly after receipt by the Swingline Lender of any Swingline Loan Notice, the Swingline Lender will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has also received such Swingline Loan Notice and, if not, the Swingline Lender will notify the Administrative Agent (by telephone or in writing) of the contents thereof. Unless the Swingline Lender has received notice (by telephone or in writing) from the Administrative Agent (including at the request of any Revolving Lender) prior to 2:00 p.m. on the date of the proposed Swingline Borrowing (1) directing the Swingline Lender not to make such Swingline Loan as a result of the limitations set forth in the first proviso to the first sentence of Section 2.04(a), or (2) that one or more of the applicable conditions specified in Article IV is not then satisfied, then, subject to the terms and conditions hereof, the Swingline Lender may make the amount of its Swingline Loan available to the Borrower at its office by crediting the account of the Borrower on the books of the Swingline Lender in immediately available funds. (c) Refinancing of Swingline Loans. (i) The Swingline Lender at any time in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes the Swingline Lender to so request on its behalf), that each Revolving Lender make a Base Rate Loan in an amount equal to such Lender’s Applicable Revolving Percentage of the amount of Swingline Loans then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Loan Notice for purposes hereof) and in accordance with the requirements of Section 2.02, without regard to the minimum and multiples specified therein for the principal amount of Base Rate Loans, but subject to the unutilized portion

57 [Harmonic] Credit Agreement #231730035 of the Revolving Facility and the conditions set forth in Section 4.02. The Swingline Lender shall furnish the Borrower with a copy of the applicable Loan Notice promptly after delivering such notice to the Administrative Agent. Each Revolving Lender shall make an amount equal to its Applicable Revolving Percentage of the amount specified in such Loan Notice available to the Administrative Agent in immediately available funds (and the Administrative Agent may apply Cash Collateral available with respect to the applicable Swingline Loan) for the account of the Swingline Lender at the Administrative Agent’s Office not later than 1:00 p.m. on the day specified in such Loan Notice, whereupon, subject to Section 2.04(c)(ii), each Revolving Lender that so makes funds available shall be deemed to have made a Base Rate Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Swingline Lender. (ii) Notwithstanding anything to the contrary in the foregoing, if for any reason any Swingline Loan cannot be refinanced by such a Revolving Borrowing in accordance with Section 2.04(c)(i) (including, without limitation, the failure to satisfy the conditions set forth in Section 4.02), the request for Base Rate Loans submitted by the Swingline Lender as set forth herein shall be deemed to be a request by the Swingline Lender that each of the Revolving Lenders fund its risk participation in the relevant Swingline Loan and each Revolving Lender’s payment to the Administrative Agent for the account of the Swingline Lender pursuant to Section 2.04(c)(i) shall be deemed payment in respect of such participation. (iii) If any Revolving Lender fails to make available to the Administrative Agent for the account of the Swingline Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.04(c) by the time specified in Section 2.04(c)(i), the Swingline Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swingline Lender at a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by the Swingline Lender in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Swingline Lender in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Revolving Loan included in the relevant Revolving Borrowing or funded participation in the relevant Swingline Loan, as the case may be. A certificate of the Swingline Lender submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (c)(iii) shall be conclusive absent manifest error. (iv) Each Revolving Lender’s obligation to make Revolving Loans or to purchase and fund risk participations in Swingline Loans pursuant to this Section 2.04(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Swingline Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided that each Revolving Lender’s obligation to make Revolving Loans pursuant to this Section 2.04(c) is subject to the conditions set forth in Section 4.02 (other than delivery by the Borrower of a Loan Notice). No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay Swingline Loans, together with interest as provided herein.

58 [Harmonic] Credit Agreement #231730035 (d) Repayment of Participations. (i) At any time after any Revolving Lender has purchased and funded a risk participation in a Swingline Loan, if the Swingline Lender receives any payment on account of such Swingline Loan, the Swingline Lender will distribute to such Revolving Lender its Applicable Revolving Percentage thereof in the same funds as those received by the Swingline Lender. (ii) If any payment received by the Swingline Lender in respect of principal or interest on any Swingline Loan is required to be returned by the Swingline Lender under any of the circumstances described in Section 11.05 (including pursuant to any settlement entered into by the Swingline Lender in its discretion), each Revolving Lender shall pay to the Swingline Lender its Applicable Revolving Percentage thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the Federal Funds Rate. The Administrative Agent will make such demand upon the request of the Swingline Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement. (e) Interest for Account of Swingline Lender. The Swingline Lender shall be responsible for invoicing the Borrower for interest on the Swingline Loans. Until each Revolving Lender funds its Base Rate Loan or risk participation pursuant to this Section 2.04 to refinance such Revolving Lender’s Applicable Revolving Percentage of any Swingline Loan, interest in respect of such Applicable Revolving Percentage shall be solely for the account of the Swingline Lender. (f) Payments Directly to Swingline Lender. The Borrower shall make all payments of principal and interest in respect of the Swingline Loans directly to the Swingline Lender. 2.05 Prepayments. (a) Optional. (i) The Borrower may, upon notice to the Administrative Agent pursuant to delivery to the Administrative Agent of a Notice of Loan Prepayment, at any time or from time to time voluntarily prepay Term Loans and Revolving Loans in whole or in part without premium or penalty, subject to Section 3.05; provided that, unless otherwise agreed by the Administrative Agent (i) such notice must be received by the Administrative Agent not later than 12:00 p.m. (A) two Business Days prior to any date of prepayment of Term SOFR Loans and (B) on the date of prepayment of Base Rate Loans; (ii) any prepayment of Term SOFR Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment and the Type(s) of Loans to be prepaid and, if Term SOFR Loans are to be prepaid, the Interest Period(s) of such Loans. The Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s ratable portion of such prepayment (based on such Lender’s Applicable Percentage in respect of the relevant Facility). If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein; provided that such notice may be conditional on the effectiveness of a replacement credit agreement

59 [Harmonic] Credit Agreement #231730035 (or other similar document) or the receipt of proceeds of the issuance of Indebtedness or some other identifiable event or condition and may be revoked by the Company (by written notice to the Administrative Agent at least one (1) Business Day prior to the specified effective date). Any prepayment of any Term SOFR Loan shall be accompanied by all accrued interest on the amount prepaid, together with any additional amounts required pursuant to Section 3.05. Each prepayment of the outstanding Term Loans pursuant to this Section 2.05(a) shall be applied to the principal repayment installments thereof in inverse order of maturity. Subject to Section 2.15, such prepayments shall be paid to the Lenders in accordance with their respective Applicable Percentages in respect of each of the relevant Facilities. (ii) The Borrower may, upon notice to the Swingline Lender pursuant to delivery to the Swingline Lender of a Notice of Loan Prepayment (with a copy to the Administrative Agent), at any time or from time to time, voluntarily prepay Swingline Loans in whole or in part without premium or penalty; provided that, unless otherwise agreed by the Swingline Lender, (A) such notice must be received by the Swingline Lender and the Administrative Agent not later than 1:00 p.m. on the date of the prepayment, and (B) any such prepayment shall be in a minimum principal amount of $100,000 or a whole multiple of $100,000 in excess hereof (or, if less, the entire principal thereof then outstanding). Each such notice shall specify the date and amount of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein; provided that such notice may be conditional on the effectiveness of a replacement credit agreement (or other similar document) or the receipt of proceeds of the issuance of Indebtedness or some other identifiable event or condition and may be revoked by the Company (by written notice to the Administrative Agent at least one (1) Business Day prior to the specified effective date). (b) Mandatory. (i) Dispositions and Involuntary Dispositions. The Borrower shall prepay the Term Loans as hereinafter provided in an aggregate amount equal to (a) 100% of the Net Cash Proceeds received by any Loan Party or any Subsidiary from all Dispositions (other than Permitted Transfers, Dispositions permitted by Sections 7.05(d) (other than such Dispositions pursuant to Section 7.04(g)), 7.03 and 7.05(e)) and Involuntary Dispositions within three (3) days of the date of such Disposition or Involuntary Disposition; provided, however, that so long as no Default shall have occurred and be continuing, such Net Cash Proceeds shall not be required to be so applied (A) until the aggregate amount of the Net Cash Proceeds derived from any such Disposition or Involuntary Disposition in any fiscal year of the Borrower is equal to or greater than $5,000,000 and (B) at the election of the Borrower (as notified by the Borrower to the Administrative Agent) to the extent such Loan Party or such Subsidiary reinvests all or any portion of such Net Cash Proceeds in like assets or other assets useful to the business of the Company and its Subsidiaries (but specifically excluding current assets as classified by GAAP) within three hundred sixty- five (365) days after the receipt of such Net Cash Proceeds; provided that, if such Net Cash Proceeds shall have not been so reinvested within such period, such Net Cash Proceeds shall be immediately applied to prepay the Term Loans and (b)(i) 50% of the Net Cash Proceeds from the Video Business Sale (if, on a Pro Forma Basis after giving effect to such Disposition, the Consolidated Net Leverage Ratio as of such date is greater than 3.00:1.00) or (ii) 0% (if, on a Pro Forma Basis after giving effect to such Disposition, the Consolidated Net Leverage Ratio as of such date is equal to or less than 3.00:1.00).

Each prepayment of Loans pursuant to the foregoing provisions of clauses (i) and (ii) of this Section 2.05(b) shall be applied to the principal repayment installments of the Term Loan in inverse order of maturity but specifically excluding the final principal installment on the Maturity Date. Subject to Section 2.15, such prepayments shall be paid to the Lenders in accordance with their respective Applicable Percentages in respect of the Term Facility. (iv) Revolving Outstandings. If for any reason the Total Revolving Outstandings at any time exceed the Revolving Facility at such time, the Borrower shall immediately prepay Revolving Loans, Swingline Loans and L/C Borrowings and/or Cash Collateralize the L/C Obligations in an aggregate amount equal to such excess; provided that the Borrower shall not be required to Cash Collateralize the L/C Obligations pursuant to this Section 2.05(b) unless, after the prepayment of the Revolving Loans and Swingline Loans, the Total Revolving Outstandings exceed the Revolving Facility at such time. Within the parameters of the applications set forth above, prepayments pursuant to this Section 2.05(b) shall be applied first to Base Rate Loans and then to Term SOFR Loans in direct order of Interest Period maturities. All prepayments under this Section 2.05(b) shall be subject to Section 3.05, but otherwise without premium or penalty, and shall be accompanied by interest on the principal amount prepaid through the date of prepayment. 2.06 Termination or Reduction of Commitments.

The Borrower may, upon notice to the Administrative Agent, terminate the Revolving Facility, the Letter of Credit Sublimit or the Swingline Sublimit, or from time to time permanently reduce the Revolving Facility, the Letter of Credit Sublimit or the Swingline Sublimit; provided that (i) any such notice shall be received by the Administrative Agent not later than 12:00 p.m. five (5) Business Days prior to the date of termination or reduction, (ii) any such partial reduction shall be in an aggregate amount of $10,000,000 or any whole multiple of $1,000,000 in excess thereof and (iii) the Borrower shall not terminate or reduce (A) the Revolving Facility if, after giving effect thereto and to any concurrent prepayments hereunder, the Total Revolving Outstandings would exceed the Revolving Facility, (B) the Letter of Credit Sublimit if, after giving effect thereto, the Outstanding Amount of L/C Obligations not fully Cash Collateralized hereunder would exceed the Letter of Credit Sublimit, or (C) the Swingline Sublimit if, after giving effect thereto and to any concurrent prepayments hereunder, the Outstanding Amount of Swingline Loans would exceed the Letter of Credit Sublimit. In addition, during the Availability Period in respect of the Term Facility, the Borrower may, upon notice to the Administrative Agent as set forth above, from time to time terminate (in whole or in part) the unused portion of the aggregate Term Commitments; provided that any such notice of termination or permanent reduction may be conditional on the effectiveness of a replacement credit agreement (or other similar document) or the receipt of proceeds of the issuance of Indebtedness or some other identifiable event or condition and may be revoked by the Company (by written notice to the Administrative Agent at least one (1) Business Day prior to the specified effective date). (b) Mandatory.

61 [Harmonic] Credit Agreement #231730035 (i) The aggregate Term Commitments shall be automatically and permanently reduced to zero on the last day of the Availability Period for the Term Facility. (ii) If after giving effect to any reduction or termination of Revolving Commitments under this Section 2.06, the Letter of Credit Sublimit or the Swingline Sublimit exceeds the Revolving Facility at such time, the Letter of Credit Sublimit or the Swingline Sublimit, as the case may be, shall be automatically reduced by the amount of such excess. (c) Application of Commitment Reductions; Payment of Fees. The Administrative Agent will promptly notify the Lenders of any termination or reduction of the Letter of Credit Sublimit, Swingline Sublimit or the Revolving Commitment under this Section 2.06. Upon any reduction of the Revolving Commitments, the Revolving Commitment of each Revolving Lender shall be reduced by such Lender’s Applicable Revolving Percentage of such excess. All fees in respect of the Revolving Facility accrued until the effective date of any termination of the Revolving Facility shall be paid on the effective date of such termination. 2.07 Repayment of Loans. (a) Term Loans. The Borrower shall repay to the Term Lenders the percentage of the aggregate principal amount of all Term Loans outstanding at the end of the Availability Period for the Term Loans in the percentage of such Term Loans set forth opposite such dates, unless accelerated sooner pursuant to Section 8.02; Payment Dates Principal Repayment Installments December 31, 2023 0% March 31, 2024 0% June 30, 2024 0% September 30, 2024 0% December 31, 2024 1.25% March 31, 2025 1.25% June 30, 2025 1.25% September 30, 2025 1.25% December 31, 2025 1.875% March 31, 2026 1.875% June 30, 2026 1.875% September 30, 2026 1.875% December 31, 2026 1.875% March 31, 2027 1.875% June 30, 2027 1.875% September 30, 2027 1.875% December 31, 2027 2.50% March 31, 2028 2.50% June 30, 2028 2.50% September 30, 2028 2.50% provided, however, that (i) the final principal repayment installment of the Term Loans shall be repaid on the Maturity Date for the Term Facility and in any event shall be in an amount equal to the aggregate principal amount of all Term Loans outstanding on such date, (ii) if any principal

62 [Harmonic] Credit Agreement #231730035 repayment installment to be made by the Borrower (other than principal repayment installments on Term SOFR Loans) shall come due on a day other than a Business Day, such principal repayment installment shall be due on the next succeeding Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be and (iii) if any principal repayment installment to be made by the Borrower on a Term SOFR Loan shall come due on a day other than a Business Day, such principal repayment installment shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such principal repayment installment into another calendar month, in which event such principal repayment installment shall be due on the immediately preceding Business Day. (b) Revolving Loans. The Borrower shall repay to the Revolving Lenders on the Maturity Date for the Revolving Facility the aggregate principal amount of all Revolving Loans outstanding on such date. (c) Swingline Loans. The Borrower shall repay each Swingline Loan on the earlier to occur of (i) the date ten (10) Business Days after such Loan is made and (ii) the Maturity Date for the Revolving Facility. 2.08 Interest and Default Rate. (a) Interest. Subject to the provisions of Section 2.08(b), (i) each Term SOFR Loan under such Facility shall bear interest on the outstanding principal amount thereof for each Interest Period from the applicable Borrowing date at a rate per annum equal to the Term SOFR for such Interest Period plus the Applicable Rate under such Facility; (ii) each Base Rate Loan under a Facility shall bear interest on the outstanding principal amount thereof from the applicable Borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate for such Facility; and (iii) each Swingline Loan shall bear interest on the outstanding principal amount thereof from the applicable Borrowing date at a rate per annum equal to the Base Rate for the Revolving Facility plus the Applicable Rate. To the extent that any calculation of interest or any fee required to be paid under this Agreement shall be based on (or result in) a calculation that is less than zero, such calculation shall be deemed zero for purposes of this Agreement. (b) Default Rate. (i) If any amount of principal of any Loan is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by Applicable Laws. (ii) If any amount (other than principal of any Loan) payable by the Borrower under any Loan Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then upon the request of the Required Lenders such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by Applicable Laws. (iii) Upon the request of the Required Lenders, while any Event of Default exists (including a payment default), all outstanding Obligations (including Letter of Credit Fees) may accrue at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by Applicable Laws.

63 [Harmonic] Credit Agreement #231730035 (iv) Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand. (c) Interest Payments. Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law. 2.09 Fees. In addition to certain fees described in Section 2.03: (a) Commitment Fee. The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Applicable Percentage, a commitment fee equal to: (i) the Applicable Rate times the actual daily amount by which the Revolving Facility exceeds the sum of: (x) the Outstanding Amount of Revolving Loans and (y) the Outstanding Amount of L/C Obligations, subject to adjustment as provided in Section 2.15. For the avoidance of doubt, the Outstanding Amount of Swingline Loans shall not be counted towards or considered usage of the Revolving Facility for purposes of determining the commitment fee; and (ii) the Applicable Rate times the actual daily amount by which the aggregate Term Commitments exceed the Outstanding Amount of Term Loans, in each case, subject to adjustment as provided in Section 2.15. The commitment fee shall accrue at all times during the relevant Availability Period, including at any time during which one or more of the conditions in Article IV is not met, and shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the Closing Date, and, in the case of the commitment fee with respect to the Revolving Facility, on the last day of the Availability Period for the Revolving Facility or, in the case of the commitment fee with respect to the Term Facility, on the last day of the Availability Period for the Term Facility. The commitment fee shall be calculated quarterly in arrears, and if there is any change in the Applicable Rate during any quarter, the actual daily amount shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect. (b) Other Fees. (i) The Borrower shall pay to the Administrative Agent and the Arranger for its own account fees in the amounts and at the times specified in the Fee Letter. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever. (ii) The Borrower shall pay to the Lenders such fees as shall have been separately agreed upon in writing in the amounts and at the times so specified. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever. (iii) The Borrower shall pay to the Administrative Agent, for the account of each of the Term Lenders, on a pro rata basis in accordance with their Term Commitments,

64 [Harmonic] Credit Agreement #231730035 a funding fee (the “Funding Fee”) in an aggregate amount equal to 0.20% of the aggregate principal amount of Term Loans advanced hereunder (whether in one draw or multiple draws). The Funding Fee will be (x) fully earned as of the date of each Credit Extension for such Term Loans (with respect to that portion of the Term Loans advanced on such date) by the Lenders under the Term Facility and (y) shall be due and payable in full on the last day of the Availability Period with respect to the Term Loans. 2.10 Computation of Interest and Fees; Retroactive Adjustments of Applicable Rate. (a) Computation of Interest and Fees. All computations of interest for Base Rate Loans (including Base Rate Loans determined by reference to Term SOFR) shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest shall be made on the basis of a three hundred sixty (360) day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365 day year). Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall, subject to Section 2.12(a), bear interest for one (1) day. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error. (b) Financial Statement Adjustments or Restatements. If, as a result of any restatement of or other adjustment to the financial statements of the Company and its Subsidiaries or for any other reason, the Company, or the Lenders determine that (i) the Consolidated Net Leverage Ratio as calculated by the Company as of any applicable date was inaccurate and (ii) a proper calculation of the Consolidated Net Leverage Ratio would have resulted in higher pricing for such period, the Borrower shall immediately and retroactively be obligated to pay to the Administrative Agent for the account of the applicable Lenders or the L/C Issuer, as the case may be, promptly on demand by the Administrative Agent (or, after the occurrence of an actual or deemed entry of an order for relief with respect to the Borrower under the Bankruptcy Code of the United States, automatically and without further action by the Administrative Agent, any Lender or the L/C Issuer), an amount equal to the excess of the amount of interest and fees that should have been paid for such period over the amount of interest and fees actually paid for such period. This clause (b) shall not limit the rights of the Administrative Agent, any Lender or the L/C Issuer, as the case may be, under any provision of this Agreement to payment of any Obligations hereunder at the Default Rate or under Article VIII. The Borrower’s obligations under this clause (b) shall survive the termination of the Aggregate Commitments and the repayment of all other Obligations hereunder. 2.11 Evidence of Debt. (a) Maintenance of Accounts. The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender in the ordinary course of business. The Administrative Agent shall maintain the Register in accordance with Section 11.06(c). The accounts or records maintained by each Lender shall be conclusive absent manifest error of the amount of the Credit Extensions made by the Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the Register, the Register shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the Borrower shall execute and deliver to such Lender (through the Administrative Agent) a Note, which shall evidence such

65 [Harmonic] Credit Agreement #231730035 Lender’s Loans in addition to such accounts or records. Each Lender may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of its Loans and payments with respect thereto. (b) Maintenance of Records. In addition to the accounts and records referred to in Section 2.11(a), each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swingline Loans. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. 2.12 Payments Generally; Administrative Agent’s Clawback. (a) General. All payments to be made by the Borrower shall be made free and clear of and without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by the Borrower hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the Administrative Agent’s Office in Dollars and in immediately available funds not later than 2:00 p.m. on the date specified herein. The Administrative Agent will promptly distribute to each Lender its Applicable Percentage in respect of the relevant Facility (or other applicable share as provided herein) of such payment in like funds as received by wire transfer to such Lender’s Lending Office. All payments received by the Administrative Agent after 2:00 p.m. shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. Subject to Section 2.07(a) and as otherwise specifically provided for in this Agreement, if any payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be. (b) (i) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing of Term SOFR Loans (or, in the case of any Borrowing of Base Rate Loans, prior to 1:00 p.m. on the date of such Borrowing) that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.02 (or, in the case of a Borrowing of Base Rate Loans, that such Lender has made such share available in accordance with and at the time required by Section 2.02) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in immediately available funds with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (A) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Administrative Agent in connection with the foregoing, and (B) in the case of a payment to be made by the Borrower, the interest rate applicable to Base Rate Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Borrowing to the

66 [Harmonic] Credit Agreement #231730035 Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent. (ii) Payments by Borrower; Presumptions by Administrative Agent. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the L/C Issuer hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Appropriate Lenders or the L/C Issuer, as the case may be, the amount due. With respect to any payment that the Administrative Agent makes for the account of the Lenders or the L/C Issuer hereunder as to which the Administrative Agent determines (which determination shall be conclusive absent manifest error) that any of the following applies (such payment referred to as the “Rescindable Amount”): (1) the Borrower has not in fact made such payment; (2) the Administrative Agent has made a payment in excess of the amount so paid by the Borrower (whether or not then owed); or (3) the Administrative agent has for any reason otherwise erroneously made such payment; then each of the Appropriate Lenders or the L/C Issuer, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the Rescindable Amount so distributed to such Lender or the L/C Issuer, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. A notice of the Administrative Agent to any Lender or the Borrower with respect to any amount owing under this clause (b) shall be conclusive, absent manifest error. (c) Failure to Satisfy Conditions Precedent. If any Lender makes available to the Administrative Agent funds for any Loan to be made by such Lender as provided in the foregoing provisions of this Article II, and such funds are not made available to the Borrower by the Administrative Agent because the conditions to the applicable Credit Extension set forth in Article IV are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest. (d) Obligations of Lenders Several. The obligations of the Lenders hereunder to make Term Loans and Revolving Loans, to fund participations in Letters of Credit and Swingline Loans and to make payments pursuant to Section 11.04(c) are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any payment under Section 11.04(c) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to purchase its participation or to make its payment under Section 11.04(c). (e) Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner. (f) Pro Rata Treatment. Except to the extent otherwise provided herein: (i) each Borrowing (other than Swingline Borrowings) shall be made from the Appropriate Lenders, each

67 [Harmonic] Credit Agreement #231730035 payment of fees under Section 2.09 and Section 2.03 shall be made for account of the Appropriate Lenders, and each termination or reduction of the amount of the Commitments shall be applied to the respective Commitments of the Lenders, pro rata according to the amounts of their respective Commitments; (ii) each Borrowing shall be allocated pro rata among the Lenders according to the amounts of their respective Commitments (in the case of the making of Revolving Loans) or their respective Loans that are to be included in such Borrowing (in the case of conversions and continuations of Loans); (iii) each payment or prepayment of principal of Loans by the Borrower shall be made for account of the Appropriate Lenders pro rata in accordance with the respective unpaid principal amounts of the Loans held by them; and (iv) each payment of interest on Loans by the Borrower shall be made for account of the Appropriate Lenders pro rata in accordance with the amounts of interest on such Loans then due and payable to the respective Appropriate Lenders. (g) Insufficient Funds. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, L/C Borrowings, interest and fees then due hereunder, such funds shall be applied (i) first, toward payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, toward payment of principal and L/C Borrowings then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and L/C Borrowings then due to such parties. 2.13 Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of (a) Obligations in respect of any of the Facilities due and payable to such Lender hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations due and payable to such Lender at such time to (ii) the aggregate amount of the Obligations in respect of the Facilities due and payable to all Lenders hereunder and under the other Loan Documents at such time) of payments on account of the Obligations in respect of the Facilities due and payable to all Lenders hereunder and under the other Loan Documents at such time obtained by all the Lenders at such time or (b) Obligations in respect of any of the Facilities owing (but not due and payable) to such Lender hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations owing (but not due and payable) to such Lender at such time to (ii) the aggregate amount of the Obligations in respect of the Facilities owing (but not due and payable) to all Lenders hereunder and under the other Loan Documents at such time) of payments on account of the Obligations in respect of the Facilities owing (but not due and payable) to all Lenders hereunder and under the other Loan Documents at such time obtained by all of the Lenders at such time, then, in each case under clauses (a) and (b) above, the Lender receiving such greater proportion shall (A) notify the Administrative Agent of such fact, and (B) purchase (for cash at face value) participations in the Loans and sub-participations in L/C Obligations and Swingline Loans of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of Obligations in respect of the Facilities then due and payable to the Lenders or owing (but not due and payable) to the Lenders, as the case may be, provided that: (i) if any such participations or sub-participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations or sub- participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and (ii) the provisions of this Section 2.13 shall not be construed to apply to (A) any payment made by or on behalf of the Borrower pursuant to and in accordance with

68 [Harmonic] Credit Agreement #231730035 the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), (B) the application of Cash Collateral provided for in Section 2.14, or (C) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or sub-participations in L/C Obligations or Swingline Loans to any assignee or participant, other than an assignment to any Loan Party or any Affiliate thereof (as to which the provisions of this Section 2.13 shall apply). Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under Applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against such Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Loan Party in the amount of such participation. 2.14 Cash Collateral. (a) Obligation to Cash Collateralize. At any time there shall exist a Defaulting Lender, within one Business Day following the written request of the Administrative Agent or the L/C Issuer (with a copy to the Administrative Agent), the Borrower shall Cash Collateralize the L/C Issuer’s Fronting Exposure with respect to such Defaulting Lender (determined after giving effect to Section 2.15(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the Minimum Collateral Amount. (b) Grant of Security Interest. The Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the Administrative Agent, the L/C Issuer and the Lenders, and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as Collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 2.14(c). If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent or the L/C Issuer as herein provided, or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the Borrower will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (determined in the case of Cash Collateral provided pursuant to Section 2.15(a)(v), after giving effect to Section 2.15(a)(v) and any Cash Collateral provided by the Defaulting Lender). All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in one or more Controlled Accounts at Citibank. The Borrower shall pay on demand therefor from time to time all customary account opening, activity and other administrative fees and charges in connection with the maintenance and disbursement of Cash Collateral. (c) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under any of this Section 2.14 or Sections 2.03, 2.05, 2.15 or 8.02 in respect of Letters of Credit shall be held and applied to the satisfaction of the specific L/C Obligations, obligations to fund participations therein (including, as to Cash Collateral provided by a Revolving Lender that is a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein. (d) Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or to secure other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including

69 [Harmonic] Credit Agreement #231730035 by the termination of Defaulting Lender status of the applicable Revolving Lender (or, as appropriate, its assignee following compliance with Section 11.06(b)(vi))) or (ii) the determination by the Administrative Agent and the L/C Issuer that there exists excess Cash Collateral; provided that (A) any such release shall be without prejudice to, and any disbursement or other transfer of Cash Collateral shall be and remain subject to, any other Lien conferred under the Loan Documents and the other applicable provisions of the Loan Documents, and (B) the Person providing Cash Collateral and the L/C Issuer may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations. 2.15 Defaulting Lenders. (a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by Applicable Law: (i) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of “Required Lenders” and Section 11.01. (ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VIII or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 11.08 shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the L/C Issuer or the Swingline Lender hereunder; third, to Cash Collateralize the L/C Issuer’s Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.14; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to (A) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (B) Cash Collateralize the L/C Issuer’s future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 2.14; sixth, to the payment of any amounts owing to the Lenders, the L/C Issuer or Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the L/C Issuer or the Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise as may be required under the Loan Documents in connection with any Lien conferred thereunder or directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or L/C Borrowings in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 4.02 were satisfied or waived, such payment shall be applied solely to

70 [Harmonic] Credit Agreement #231730035 pay the Loans of, and L/C Obligations owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or L/C Obligations owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in L/C Obligations and Swingline Loans are held by the Lenders pro rata in accordance with the Commitments hereunder without giving effect to Section 2.15(a)(v). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.15(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto. (iii) Certain Fees. (A) Fees. No Defaulting Lender shall be entitled to receive any fee payable under Section 2.09(a) for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender). (B) Letter of Credit Fees. Each Defaulting Lender shall be entitled to receive Letter of Credit Fees for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Applicable Revolving Percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.14. (C) Defaulting Lender Fees. With respect to any Letter of Credit Fee not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrower shall (1) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in L/C Obligations or Swingline Loans that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (2) pay to the L/C Issuer and the Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such L/C Issuer’s or Swingline Lender’s Fronting Exposure to such Defaulting Lender, and (3) not be required to pay the remaining amount of any such fee. (iv) Reallocation of Applicable Revolving Percentages to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation in L/C Obligations and Swingline Loans shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Applicable Revolving Percentages (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that such reallocation does not cause the aggregate Revolving Exposure of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s Revolving Commitment. Subject to Section 11.20, no reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation. (v) Cash Collateral, Repayment of Swingline Loans. If the reallocation described in clause (a)(v) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under Applicable Law, (A) first, prepay Swingline Loans in an amount equal to the Swingline Lender’s

71 [Harmonic] Credit Agreement #231730035 Fronting Exposure and (B) second, Cash Collateralize the L/C Issuer’s Fronting Exposure in accordance with the procedures set forth in Section 2.14. (b) Defaulting Lender Cure. If the Borrower, the Administrative Agent, the Swingline Lender and the L/C Issuer agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held pro rata by the Lenders in accordance with their Revolving Commitments (without giving effect to Section 2.15(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided further that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. (c) New Swingline Loans/Letters of Credit. So long as any Revolving Lender is a Defaulting Lender, (i) the Swingline Lender shall not be required to fund any Swingline Loans unless it is satisfied that it will have no Fronting Exposure after giving effect to such Swingline Loan and (ii) the L/C Issuer shall not be required to issue, extend, increase, reinstate or renew any letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto. 2.16 Increase in Commitments. Borrower Request. The Company may by written notice to the Administrative Agent elect to request (x) prior to the Maturity Date for the Revolving Facility, an increase to the existing Revolving Commitments (each, an “Incremental Revolving Commitment”) and/or (y) the establishment of one or more new term loan commitments (each, an “Incremental Term Commitment”), by an aggregate amount not in excess of an amount equal to (i) $100,000,000 plus (ii) an additional amount such that, after giving Pro Forma Effect to the incurrence of such Incremental Revolving Commitment (and assuming all Incremental Revolving Commitments are fully drawn) and/or the Incremental Term Loans, the Consolidated Net Leverage Ratio is no greater than 2.50:1.00 (for the avoidance of doubt, any incurrence under clause (i) above shall not be given pro forma effect for purposes of determining the Consolidated Net Leverage Ratio for purposes of effectuating the incurrence under clause (ii)). Each such notice shall specify (i) the date (each, an “Increase Effective Date”) on which the Company proposes that the Incremental Commitments shall be effective, which shall be a date not less than ten (10) Business Days after the date on which such notice is delivered to the Administrative Agent and (ii) the identity of each Eligible Assignee to whom the Company proposes any portion of such Incremental Commitments be allocated and the amounts of such allocations; provided that any existing Lender approached to provide all or a portion of the Incremental Commitments may elect or decline, in its sole discretion, to provide such Incremental Commitment. (i) Each Incremental Commitment shall be in an aggregate amount of $30,000,000 or any whole multiple of $1,000,000 in excess thereof (provided that such amount may be less than $30,000,000 if such amount represents all remaining availability under the aggregate limit in respect of Incremental Commitments set forth in above) and (ii) no more than three (3) Incremental Commitments may be requested during the term of this Agreement. (a) Conditions. The Incremental Commitments shall become effective as of the Increase Effective Date; provided that (and, in the case of an Incremental Term Loan incurred solely to finance a substantially concurrent Limited Condition Acquisition, subject to Section 1.09):

72 [Harmonic] Credit Agreement #231730035 (i) each of the conditions set forth in Section 4.02 shall be satisfied; (ii) no Default shall have occurred and be continuing or would result from the borrowings to be made on the Increase Effective Date; (iii) the representations and warranties contained in Article V and the other Loan Documents are true and correct in all material respects on and as of the Increase Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they shall have been true and correct in all material respects as of such earlier date, and except that for purposes of this Section 2.15(a), the representations and warranties contained in Section 5.05(a) and Section 5.05(b) shall be deemed to refer to the most recent financial statements furnished pursuant to clauses (a) and (b), respectively, of Section 6.01. (iv) on a Pro Forma Basis (assuming, in the case of Incremental Revolving Commitments, that such Incremental Revolving Commitments are fully drawn), the Borrower shall be in compliance with each of the covenants set forth in Section 7.11; (v) the Borrower shall make any breakage payments in connection with any adjustment of Revolving Loans pursuant to Section 3.05; (vi) the Borrower shall deliver or cause to be delivered officer’s certificates and legal opinions of the type delivered on the Closing Date to the extent reasonably requested by, and in form and substance reasonably satisfactory to, the Administrative Agent; and (vii) (A) upon the reasonable request of any Lender made at least seven (7) days prior to the Increase Effective Date, the Company shall have provided to such Lender, and such Lender shall be reasonably satisfied with, the documentation and other information so requested in connection with applicable “know your customer” and anti-money-laundering rules and regulations, including, without limitation, the PATRIOT Act, in each case at least three (3) Business Days prior to the Increase Effective Date and (B) at least three (3) Business Days prior to the Increase Effective Date, any Loan Party that qualifies as a “legal entity customer” under the Beneficial Ownership Regulation shall have delivered, to each Lender that so requests, a Beneficial Ownership Certification in relation to such Loan Party. (b) Terms of New Loans and Commitments. The terms and provisions of Loans made pursuant to Incremental Commitments shall be as follows: (i) terms and provisions of Incremental Term Loans shall be, except as otherwise set forth herein or in the Increase Joinder, identical to the Term Loans (it being understood that Incremental Term Loans may be a part of the Term Loans) and to the extent that the terms and provisions of Incremental Term Loans are not identical to the Term Loans (except to the extent permitted by clause (iii), (iv) or (v) below) they shall be reasonably satisfactory to the Administrative Agent; provided that in any event the Incremental Term Loans must comply with clauses (iii), (iv) and (v) below; (ii) the terms and provisions of Revolving Loans made pursuant to new Commitments shall be identical to the Revolving Loans; (iii) the weighted average life to maturity of any Incremental Term Loans shall be no shorter than the remaining weighted average life to maturity of the then existing Term Loans;

73 [Harmonic] Credit Agreement #231730035 (iv) the maturity date of Incremental Term Loans (the “Incremental Term Loan Maturity Date”) shall not be earlier than the than the Maturity Date; (v) the Applicable Rate for Incremental Term Loans shall be determined by the Company and the Lenders of the Incremental Term Loans; The Incremental Commitments shall be effected by a joinder agreement (the “Increase Joinder”) executed by the Borrower, the Administrative Agent and each Lender making such Incremental Commitment, in form and substance reasonably satisfactory to each of them. Notwithstanding the provisions of Section 11.01, the Increase Joinder may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the reasonable opinion of the Administrative Agent, to effect the provisions of this Section 2.16. In addition, unless otherwise specifically provided herein, all references in Loan Documents to Revolving Loans or Term Loans shall be deemed, unless the context otherwise requires, to include references to Revolving Loans made pursuant to Incremental Revolving Commitments and Incremental Term Loans that are Term Loans, respectively, made pursuant to this Agreement. This Section 2.16 shall supersede any provisions in Section 2.13 or Section 11.01 to the contrary. (c) Adjustment of Revolving Credit Loans. To the extent the Commitments being increased on the relevant Increase Effective Date are Incremental Revolving Commitments, then each Revolving Lender that is acquiring an Incremental Revolving Commitment on the Increase Effective Date shall make a Revolving Loan, the proceeds of which will be used to prepay the Revolving Loans of the other Revolving Lenders immediately prior to such Increase Effective Date, so that, after giving effect thereto, the Revolving Loans outstanding are held by the Revolving Lenders pro rata based on their Revolving Commitments after giving effect to such Increase Effective Date. If there is a new borrowing of Revolving Loans on such Increase Effective Date, the Revolving Lenders after giving effect to such Increase Effective Date shall make such Revolving Loans in accordance with Section 2.01(b). (d) Making of New Term Loans. On any Increase Effective Date on which new Commitments for Term Loans are effective, subject to the satisfaction of the foregoing terms and conditions, each Lender of such new Commitment shall make a Term Loan to the Borrower in an amount equal to its new Commitment. (e) Equal and Ratable Benefit. The Loans and Commitments established pursuant to this Section 2.16 shall constitute Loans and Commitments under, and shall be entitled to all the benefits afforded by, this Agreement and the other Loan Documents, and shall, without limiting the foregoing, benefit equally and ratably from the Guarantees and security interests created by the Collateral Documents, except that the new Loans may be subordinated in right of payment or the Liens securing the new Loans may be subordinated, in each case, to the extent set forth in the Increase Joinder. The Loan Parties shall take any actions reasonably required by the Administrative Agent to ensure and/or demonstrate that the Lien and security interests granted by the Collateral Documents continue to be perfected under the UCC or otherwise after giving effect to the establishment of any such class of Term Loans or any such new Commitments. 2.17 Designated Borrowers. (a) Designated Borrowers. The Company may at any time, upon not less than fifteen (15) Business Days’ notice from the Company to the Administrative Agent (or such shorter period as may be agreed by the Administrative Agent in its sole discretion), request to designate any Domestic Subsidiary that is a Material Subsidiary of the Company (an “Applicant Borrower”) as a Designated Borrower to receive Loans hereunder by delivering to the Administrative Agent (which shall promptly deliver counterparts thereof to each

If the Designated Borrower Requirements are met, the Administrative Agent shall send a notice in substantially the form of Exhibit S (a “Designated Borrower Notice”) to the Company and the Lenders specifying the effective date upon which the Applicant Borrower shall constitute a Designated Borrower for purposes hereof, whereupon each of the Lenders agrees to permit such Designated Borrower to receive Loans hereunder, on the terms and conditions set forth herein, and each of the parties agrees that such Designated Borrower otherwise shall be a Borrower for all purposes of this Agreement; provided that no Loan Notice or Letter of Credit Application may be submitted by or on behalf of such Designated Borrower until the date five (5) Business Days after such effective date. (b) Obligations. Except as specifically provided herein, the Secured Obligations of the Company and each of the Borrowers shall be joint and several in nature regardless of which such Person actually receives Credit Extensions hereunder or the amount of such Credit Extensions received or the manner in which the Administrative Agent, the L/C Issuer or any Lender accounts for such Credit Extensions on its books and records. (c) Appointment. Each Subsidiary of the Company that is or becomes a “Designated Borrower” pursuant to this Section 2.17 hereby irrevocably appoints the Company to act as its agent for all purposes of this Agreement and the other Loan Documents and agrees that (i) the Company may execute such documents on behalf of such Designated Borrower as the Company deems appropriate in its sole discretion and each Designated Borrower shall be obligated by all of the terms of any such document executed on its behalf, (ii) any notice or communication delivered by the Administrative Agent or the Lender to the Company shall be deemed delivered to each Designated Borrower and (iii) the Administrative Agent or the Lenders may accept, and be permitted to rely on, any document, instrument or agreement executed by the Company on behalf of each of the Loan Parties. ARTICLE III TAXES, YIELD PROTECTION AND ILLEGALITY 3.01 Taxes. (a) Defined Terms.

Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Laws. If any Applicable Laws (as determined in the good faith discretion of an applicable withholding agent) require the deduction or withholding of any Tax from any such payment by the applicable withholding agent, then the applicable withholding agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased as necessary so that after any required withholding or the making of all required deductions (including deductions applicable to additional sums payable under this Section 3.01) the applicable Recipient receives an amount equal to the sum it would have received had no such withholding or deduction been made. (c) Payment of Other Taxes by the Loan Parties. The Loan Parties shall timely pay to the relevant Governmental Authority in accordance with Applicable Law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes. (d) Tax Indemnifications. (i) Each of the Loan Parties shall, and does hereby, jointly and severally indemnify each Recipient, and shall make payment in respect thereof within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 3.01) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. (ii) Each Lender shall, and does hereby, severally indemnify and shall make payment in respect thereof within ten (10) days after demand therefor, (A) the Administrative Agent against any Indemnified Taxes attributable to such Lender (but only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (B) the Administrative Agent and the Loan Parties, as applicable, against any Taxes attributable to such Lender’s failure to comply with the provisions of Section 11.06(d) relating to the maintenance of a Participant Register and (C) the Administrative Agent and the Loan Parties, as applicable, against any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent or a Loan Party in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this clause (d)(ii).

76 [Harmonic] Credit Agreement #231730035 (e) Evidence of Payments. As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority, as provided in this Section 3.01, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of any return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. (f) Status of Lenders; Tax Documentation. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 3.01(f)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. (ii) Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person, (A) any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of IRS Form W–9 certifying that such Lender is exempt from U.S. federal backup withholding tax; (B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable: (1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed copies of IRS Form W–8BEN–E (or W–8BEN, as applicable) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W–8BEN–E (or W–8BEN, as applicable) establishing an exemption from, or reduction

77 [Harmonic] Credit Agreement #231730035 of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty; (2) executed copies of IRS Form W–8ECI; (3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit M–1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W–8BEN– E (or W–8BEN, as applicable); or (4) to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W–8IMY, accompanied by IRS Form W– 8ECI, IRS Form W–8BEN–E (or W–8BEN, as applicable), a U.S. Tax Compliance Certificate substantially in the form of Exhibit M–2 or Exhibit M–3, IRS Form W–9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit M–4 on behalf of each such direct and indirect partner; (C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies (or originals, as required) of any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by Applicable Law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and (D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from

78 [Harmonic] Credit Agreement #231730035 such payment. Solely for the purposes of this clause (f)(ii)(D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. (iii) Each Lender agrees that if any form or certification it previously delivered pursuant to this Section 3.01 expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so. (g) Treatment of Certain Refunds. Unless required by Applicable Laws, at no time shall the Administrative Agent have any obligation to file for or otherwise pursue on behalf of a Lender, or have any obligation to pay to any Lender, any refund of Taxes withheld or deducted from funds paid for the account of such Lender. If any Recipient determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified by any Loan Party or with respect to which any Loan Party has paid additional amounts pursuant to this Section 3.01, it shall pay to such Loan Party an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by such Loan Party under this Section 3.01 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) incurred by such Recipient, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that each Loan Party, upon the request of the Recipient, agrees to repay the amount paid over to such Loan Party (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Recipient in the event the Recipient is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this clause (g), in no event will the applicable Recipient be required to pay any amount to such Loan Party pursuant to this clause (g) the payment of which would place the Recipient in a less favorable net after-Tax position than such Recipient would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This clause (g) shall not be construed to require any Recipient to make available its tax returns (or any other information relating to its Taxes that it deems confidential) to any Loan Party or any other Person. (h) Survival. Each party’s obligations under this Section 3.01 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all other Obligations. 3.02 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund or charge interest with respect to any Credit Extension, or to determine or charge interest rates based upon SOFR or Term SOFR, then, upon notice thereof by such Lender to the Borrower (through the Administrative Agent), (a) any obligation of such Lender to make or continue Term SOFR Loans or to convert Base Rate Loans to Term SOFR Loans shall be suspended, and (b) if such notice asserts the illegality of such Lender making or maintaining Base Rate Loans the interest rate on which is determined by reference to the Term SOFR component of the Base Rate, the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Term SOFR component of the Base Rate, in each case until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, (i) the Borrower shall, upon demand from such Lender (with a copy

79 [Harmonic] Credit Agreement #231730035 to the Administrative Agent), prepay or, if applicable, convert all Term SOFR Loans of such Lender to Base Rate Loans (the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Term SOFR component of the Base Rate), either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Term SOFR Loan to such day, or immediately, if such Lender may not lawfully continue to maintain such Term SOFR Loans and (ii) if such notice asserts the illegality of such Lender determining or charging interest rates based upon SOFR, the Administrative Agent shall during the period of such suspension compute the Base Rate applicable to such Lender without reference to the Term SOFR component thereof until the Administrative Agent is advised in writing by such Lender that it is no longer illegal for such Lender to determine or charge interest rates based upon SOFR. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted, together with any additional amounts required pursuant to Section 3.05. 3.03 Inability to Determine Rates. (a) If in connection with any request for a Term SOFR Loan or a conversion of Base Rate Loans to Term SOFR Loans or a continuation of any of such Loans, as applicable, (i) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that (A) no Successor Rate has been determined in accordance with Section 3.03(b), and the circumstances under clause (i) of Section 3.03(b) or the Scheduled Unavailability Date has occurred, or (B) adequate and reasonable means do not otherwise exist for determining Term SOFR for any requested Interest Period with respect to a proposed Term SOFR Loan or in connection with an existing or proposed Base Rate Loan, or (ii) the Administrative Agent or the Required Lenders determine that for any reason that Term SOFR for any requested Interest Period with respect to a proposed Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, the Administrative Agent will promptly so notify the Borrower and each Lender. Thereafter, (x) the obligation of the Lenders to make or maintain Term SOFR Loans, or to convert Base Rate Loans to Term SOFR Loans, shall be suspended (to the extent of the affected Term SOFR Loans or Interest Periods), and (y) in the event of a determination described in the preceding sentence with respect to the Term SOFR component of the Base Rate, the utilization of the Term SOFR component in determining the Base Rate shall be suspended, in each case until the Administrative Agent (or, in the case of a determination by the Required Lenders described in clause (ii) of this Section 3.03(a), until the Administrative Agent upon instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, (i) the Borrower may revoke any pending request for a Borrowing of, or conversion to, or continuation of Term SOFR Loans (to the extent of the affected Term SOFR Loans or Interest Periods) or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the amount specified therein and (ii) any outstanding Term SOFR Loans shall be deemed to have been converted to Base Rate Loans immediately at the end of their respective applicable Interest Period. (b) Notwithstanding anything to the contrary in this Agreement or any other Loan Documents, but without limiting Sections 3.03(a) and (b) above, if the Administrative Agent determines (which determination shall be conclusive and binding upon all parties hereto absent manifest error), or the Borrower or Required Lenders notify the Administrative Agent (with, in the case of the Required Lenders, a copy to the Borrower) that the Borrower or Required Lenders (as applicable) have determined (which determination likewise shall be conclusive and binding upon all parties hereto absent manifest error), that:

80 [Harmonic] Credit Agreement #231730035 (i) adequate and reasonable means do not exist for ascertaining one month, three month and six month interest periods of Term SOFR, including, without limitation, because the Term SOFR Screen Rate is not available or published on a current basis and such circumstances are unlikely to be temporary; or (ii) CME or any successor administrator of the Term SOFR Screen Rate or a Governmental Authority having jurisdiction over the Administrative Agent or such administrator with respect to its publication of Term SOFR, in each case acting in such capacity, has made a public statement identifying a specific date after which one month, three month and six month interest periods of Term SOFR or the Term SOFR Screen Rate shall or will no longer be representative or made available, or permitted to be used for determining the interest rate of U.S. dollar denominated syndicated loans, or shall or will otherwise cease, provided that, at the time of such statement, there is no successor administrator that is satisfactory to the Administrative Agent, that will continue to provide such representative interest periods of Term SOFR after such specific date (the latest date on which one month, three month and six month interest periods of Term SOFR or the Term SOFR Screen Rate are no longer representative or available permanently or indefinitely, the “Scheduled Unavailability Date”); then, on a date and time determined by the Administrative Agent (any such date, the “Term SOFR Replacement Date”), which date shall be at the end of an Interest Period or on the relevant interest payment date, as applicable, for interest calculated and, solely with respect to clause (ii) above, no later than the Scheduled Unavailability Date, Term SOFR will be replaced hereunder and under any Loan Document with Daily Simple SOFR plus the SOFR Adjustment for any payment period for interest calculated that can be determined by the Administrative Agent, in each case, without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document (the “Successor Rate”). If the Successor Rate is Daily Simple SOFR plus the SOFR Adjustment, all interest payments will be payable on a monthly basis. Notwithstanding anything to the contrary herein, (i) if the Administrative Agent determines that Daily Simple SOFR is not available on or prior to the Term SOFR Replacement Date, or (ii) if the events or circumstances of the type described in Section 3.03(b)(i) or (ii) have occurred with respect to the Successor Rate then in effect, then in each case, the Administrative Agent and the Borrower may amend this Agreement solely for the purpose of replacing Term SOFR or any then current Successor Rate in accordance with this Section 3.03 at the end of any Interest Period, relevant interest payment date or payment period for interest calculated, as applicable, with an alternative benchmark rate giving due consideration to any evolving or then existing convention for similar U.S. dollar denominated credit facilities syndicated and agented in the United States for such alternative benchmark. and, in each case, including any mathematical or other adjustments to such benchmark giving due consideration to any evolving or then existing convention for similar U.S. dollar denominated credit facilities syndicated and agented in the United States for such benchmark. For the avoidance of doubt, any such proposed rate and adjustments, shall constitute a “Successor Rate”. Any such amendment shall become effective at 5:00 p.m. on the fifth Business Day after the Administrative Agent shall have posted such proposed amendment to all Lenders and the Borrower unless, prior to such time, Lenders comprising the Required Lenders have delivered to the Administrative Agent written notice that such Required Lenders object to such amendment. The Administrative Agent will promptly (in one or more notices) notify the Borrower and each Lender of the implementation of any Successor Rate.

81 [Harmonic] Credit Agreement #231730035 Any Successor Rate shall be applied in a manner consistent with market practice; provided that to the extent such market practice is not administratively feasible for the Administrative Agent, such Successor Rate shall be applied in a manner as otherwise reasonably determined by the Administrative Agent. Notwithstanding anything else herein, if at any time any Successor Rate as so determined would otherwise be less than zero percent, the Successor Rate will be deemed to be zero percent for the purposes of this Agreement and the other Loan Documents. In connection with the implementation of a Successor Rate, the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement; provided that, with respect to any such amendment effected, the Administrative Agent shall post each such amendment implementing such Conforming Changes to the Borrower and the Lenders reasonably promptly after such amendment becomes effective. (c) For purposes of this Section 3.03, those Lenders that either have not made, or do not have an obligation under this Agreement to make, the relevant Loans in Dollars shall be excluded from any determination of Required Lenders. 3.04 Increased Costs. (a) Increased Costs Generally. If any Change in Law shall: (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender or the L/C Issuer; (ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or (iii) impose on any Lender or the L/C Issuer any other condition, cost or expense affecting this Agreement or Term SOFR Loans made by such Lender or any Letter of Credit or participation therein; and the result of any of the foregoing shall be to increase the cost to such Lender of making, converting to, continuing or maintaining any Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or the L/C Issuer of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or the L/C Issuer hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or the L/C Issuer, the Borrower will pay (or cause the applicable Designated Borrower to pay) to such Lender or the L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the L/C Issuer, as the case may be, for such additional costs incurred or reduction suffered.

82 [Harmonic] Credit Agreement #231730035 (b) Capital Requirements. If any Lender or the L/C Issuer determines that any Change in Law affecting such Lender or the L/C Issuer or any Lending Office of such Lender or such Lender’s or the L/C Issuer’s holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s or the L/C Issuer’s capital or on the capital of such Lender’s or the L/C Issuer’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit issued by the L/C Issuer, to a level below that which such Lender or the L/C Issuer or such Lender’s or the L/C Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the L/C Issuer’s policies and the policies of such Lender’s or the L/C Issuer’s holding company with respect to capital adequacy), then from time to time the Borrower will pay (or cause the applicable Designated Borrower to pay) to such Lender or the L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the L/C Issuer or such Lender’s or the L/C Issuer’s holding company for any such reduction suffered. (c) Certificates for Reimbursement. A certificate of a Lender or the L/C Issuer setting forth the amount or amounts necessary to compensate such Lender or the L/C Issuer or its holding company, as the case may be, as specified in clause (a) or (b) of this Section 3.04 and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay (or cause the applicable Designated Borrower to pay) such Lender or the L/C Issuer, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof. (d) Delay in Requests. Failure or delay on the part of any Lender or the L/C Issuer to demand compensation pursuant to the foregoing provisions of this Section 3.04 shall not constitute a waiver of such Lender’s or the L/C Issuer’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or the L/C Issuer pursuant to the foregoing provisions of this Section 3.04 for any increased costs incurred or reductions suffered more than nine (9) months prior to the date that such Lender or the L/C Issuer, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the L/C Issuer’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine (9) month period referred to above shall be extended to include the period of retroactive effect thereof). 3.05 Compensation for Losses. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, the Borrower shall promptly compensate (or cause the applicable Designated Borrower to compensate) such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of: (a) any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise); (b) any failure by the Borrower (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow, continue or convert any Loan other than a Base Rate Loan on the date or in the amount notified by the Borrower or the applicable Designated Borrower; or (c) any assignment of a Term SOFR Loan on a day other than the last day of the Interest Period therefor as a result of a request by the Borrower pursuant to Section 11.13;

83 [Harmonic] Credit Agreement #231730035 including any loss of anticipated profits and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained. The Borrower shall also pay (or cause the applicable Designated Borrower to pay) any customary administrative fees charged by such Lender in connection with the foregoing. 3.06 Mitigation Obligations; Replacement of Lenders. (a) Designation of a Different Lending Office. If any Lender requests compensation under Section 3.04, or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender, the L/C Issuer, or any Governmental Authority for the account of any Lender or the L/C Issuer pursuant to Section 3.01, or if any Lender gives a notice pursuant to Section 3.02, then at the request of the Borrower, such Lender or the L/C Issuer shall, as applicable, use reasonable efforts to designate a different Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender or the L/C Issuer, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or 3.04, as the case may be, in the future, or eliminate the need for the notice pursuant to Section 3.02, as applicable, and (ii) in each case, would not subject such Lender or the L/C Issuer, as the case may be, to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender or the L/C Issuer, as the case may be. The Borrower hereby agrees to pay (or cause the applicable Designated Borrower to pay) all reasonable costs and expenses incurred by any Lender or the L/C Issuer in connection with any such designation or assignment. (b) Replacement of Lenders. If any Lender requests compensation under Section 3.04, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01 and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 3.06(a), the Borrower may replace such Lender in accordance with Section 11.13. 3.07 Survival. All of the Borrower’s obligations under this Article III shall survive termination of the Aggregate Commitments, repayment of all other Obligations hereunder, resignation of the Administrative Agent and the Facility Termination Date.

120 [Harmonic] Credit Agreement #231730035 herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any Applicable Law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties. In addition, to the extent required under the laws of any jurisdiction other than the United States of America, each of the Lenders and Secured Parties hereby grants to the Administrative Agent any required powers of attorney to execute any Collateral Document or other Loan Document governed by the laws of such jurisdiction on such Lender’s or Secured Party’s behalf. (b) Collateral Agent. The Administrative Agent shall also act as the “collateral agent” under the Loan Documents, and each of the Lenders (including in its capacities as a potential Hedge Bank and a potential Cash Management Bank) and the L/C Issuer hereby irrevocably appoints and authorizes the Administrative Agent to act as the agent of such Lender and the L/C Issuer for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Secured Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Administrative Agent, as “collateral agent” and any co-agents, sub-agents and attorneys-in-fact appointed by the Administrative Agent pursuant to Section 9.05 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent, shall be entitled to the benefits of all provisions of this Article IX and Article XI (including Section 11.04(c), as though such co-agents, sub-agents and attorneys-in-fact were the “collateral agent” under the Loan Documents) as if set forth in full herein with respect thereto. 9.02 Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of banking, trust, financial, advisory, underwriting or other business with any Loan Party or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders or to provide notice to or consent of the Lenders with respect thereto. 9.03 Exculpatory Provisions. (a) The Administrative Agent or the Arranger, as applicable, shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent or the Arranger, as applicable, and its Related Parties: (i) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing; (ii) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to

121 [Harmonic] Credit Agreement #231730035 exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or Applicable Law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and (iii) shall not have any duty or responsibility to disclose, and shall not be liable for the failure to disclose, to any Lender or the L/C Issuer any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their Affiliates that is communicated to, or in the possession of, the Administrative Agent, Arranger or any of their Related Parties in any capacity, except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent herein. (b) Neither the Administrative Agent nor any of its Related Parties shall be liable for any action taken or not taken by the Administrative Agent under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby or thereby (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary), or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 11.01 and 8.02) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and non-appealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given in writing to the Administrative Agent by the Borrower, a Lender or the L/C Issuer. (c) Neither the Administrative Agent nor any of its Related Parties have any duty or obligation to any Lender or participant or any other Person to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the Collateral Documents, (v) the value or the sufficiency of any Collateral, or (vi) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. 9.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall be fully protected in relying and shall not incur any liability for relying upon, any notice, request, certificate, communication, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall be fully protected in relying and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance, extension, renewal or increase of a Letter

122 [Harmonic] Credit Agreement #231730035 of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the L/C Issuer, the Administrative Agent may presume that such condition is satisfactory to such Lender or the L/C Issuer unless the Administrative Agent shall have received notice to the contrary from such Lender or the L/C Issuer prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Loan Parties), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. For purposes of determining compliance with the conditions specified in Section 4.01, each Lender that has signed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received notice from such Lender prior to the proposed Closing Date specifying its objections. 9.05 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article IX shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the Facilities as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and non-appealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents. 9.06 Resignation of Administrative Agent. (a) Notice. The Administrative Agent may at any time give notice of its resignation to the Lenders, the L/C Issuer and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to) on behalf of the Lenders and the L/C Issuer, appoint a successor Administrative Agent meeting the qualifications set forth above; provided that in no event shall any successor Administrative Agent be a Defaulting Lender. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date. (b) Effect of Resignation or Removal. With effect from the Resignation Effective Date (i) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders or the L/C Issuer under any of the Loan Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (ii) except for any indemnity payments or other amounts then owed to the retiring Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the L/C Issuer directly, until such time, if any, as the Required

123 [Harmonic] Credit Agreement #231730035 Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Administrative Agent (other than as provided in Section 3.01(g) and other than any rights to indemnity payments or other amounts owed to the retiring Administrative Agent as of the Resignation Effective Date), and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section 9.06). The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article XI and Section 11.04 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them (A) while the retiring Administrative Agent was acting as Administrative Agent and (B) after such resignation or removal for as long as any of them continues to act in any capacity hereunder or under the other Loan Documents, including, without limitation, (1) acting as collateral agent or otherwise holding any collateral security on behalf of any of the Secured Parties and (2) in respect of any actions taken in connection with transferring the agency to any successor Administrative Agent. (c) L/C Issuer and Swingline Lender. Any resignation or removal by Citibank as Administrative Agent pursuant to this Section 9.06 shall also constitute its resignation as L/C Issuer and Swingline Lender. If Citibank resigns as the L/C Issuer, it shall retain all the rights, powers, privileges and duties of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as the L/C Issuer and all L/C Obligations with respect thereto, including the right to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.03(c). If Citibank resigns as Swingline Lender, it shall retain all the rights of the Swingline Lender provided for hereunder with respect to Swingline Loans made by it and outstanding as of the effective date of such resignation, including the right to require the Lenders to make Base Rate Loans or fund risk participations in outstanding Swingline Loans pursuant to Section 2.04(c). Upon the appointment by the Borrower of a successor L/C Issuer or Swingline Lender hereunder (which successor shall in all cases be a Lender other than a Defaulting Lender), (i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer or Swingline Lender, as applicable, (ii) the retiring L/C Issuer and Swingline Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (iii) the successor L/C Issuer shall issue Letters of Credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to Citibank to effectively assume the obligations of Citibank with respect to such Letters of Credit. 9.07 Non-Reliance on Administrative Agent, the Arranger and the Other Lenders. Each Lender and the L/C Issuer expressly acknowledges that none of the Administrative Agent nor the Arranger has made any representation or warranty to it, and that no act by the Administrative Agent or the Arranger hereafter taken, including any consent to, and acceptance of any assignment or review of the affairs of any Loan Party or any Affiliate thereof, shall be deemed to constitute any representation or warranty by the Administrative Agent or the Arranger to any Lender or the L/C Issuer as to any matter, including whether the Administrative Agent or the Arranger have disclosed material information in their (or their Related Parties’) possession. Each Lender and the L/C Issuer represents to the Administrative Agent and the Arranger that it has, independently and without reliance upon the Administrative Agent, the Arranger, any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis of, appraisal of, and investigation into, the

124 [Harmonic] Credit Agreement #231730035 business, prospects, operations, property, financial and other condition and creditworthiness of the Loan Parties and their Subsidiaries, and all applicable bank or other regulatory Laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Borrower hereunder. Each Lender and the L/C Issuer also acknowledges that it will, independently and without reliance upon the Administrative Agent, the Arranger, any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Loan Parties. Each Lender and the L/C Issuer represents and warrants that (i) the Loan Documents set forth the terms of a commercial lending facility and (ii) it is engaged in making, acquiring or holding commercial loans in the ordinary course and is entering into this Agreement as a Lender or L/C Issuer for the purpose of making, acquiring or holding commercial loans and providing other facilities set forth herein as may be applicable to such Lender or L/C Issuer, and not for the purpose of purchasing, acquiring or holding any other type of financial instrument, and each Lender and the L/C Issuer agrees not to assert a claim in contravention of the foregoing. Each Lender and the L/C Issuer represents and warrants that it is sophisticated with respect to decisions to make, acquire and/or hold commercial loans and to provide other facilities set forth herein, as may be applicable to such Lender or such L/C Issuer, and either it, or the Person exercising discretion in making its decision to make, acquire and/or hold such commercial loans or to provide such other facilities, is experienced in making, acquiring or holding such commercial loans or providing such other facilities. 9.08 No Other Duties, Etc. Anything herein to the contrary notwithstanding, none of the titles listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, the Arranger, a Lender or the L/C Issuer hereunder. 9.09 Administrative Agent May File Proofs of Claim; Credit Bidding. (a) In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise: (i) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Secured Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the L/C Issuer and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the L/C Issuer and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the L/C Issuer and the Administrative Agent under Sections 2.03(h) and (i), 2.09, 2.10(b) and 11.04) allowed in such judicial proceeding; and (ii) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

125 [Harmonic] Credit Agreement #231730035 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and the L/C Issuer to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and the L/C Issuer, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.09, 2.10(b) and 11.04. (b) Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or the L/C Issuer any plan of reorganization, arrangement, adjustment or composition affecting the Secured Obligations or the rights of any Lender or the L/C Issuer to authorize the Administrative Agent to vote in respect of the claim of any Lender or the L/C Issuer or in any such proceeding. (c) The Secured Parties hereby irrevocably authorize the Administrative Agent, at the direction of the Required Lenders, to credit bid all or any portion of the Secured Obligations (including accepting some or all of the Collateral in satisfaction of some or all of the Secured Obligations pursuant to a deed in lieu of foreclosure or otherwise) and in such manner purchase (either directly or through one or more acquisition vehicles) all or any portion of the Collateral (i) at any sale thereof conducted under the provisions of the Bankruptcy Code of the United States, including under Sections 363, 1123 or 1129 of the Bankruptcy Code of the United States, or any similar Laws in any other jurisdictions to which a Loan Party is subject, (ii) at any other sale or foreclosure or acceptance of collateral in lieu of debt conducted by (or with the consent or at the direction of) the Administrative Agent (whether by judicial action or otherwise) in accordance with any Applicable Law. In connection with any such credit bid and purchase, the Secured Obligations owed to the Secured Parties shall be entitled to be, and shall be, credit bid on a ratable basis (with Secured Obligations with respect to contingent or unliquidated claims receiving contingent interests in the acquired assets on a ratable basis that would vest upon the liquidation of such claims in an amount proportional to the liquidated portion of the contingent claim amount used in allocating the contingent interests) in the asset or assets so purchased (or in the Equity Interests or debt instruments of the acquisition vehicle or vehicles that are used to consummate such purchase). In connection with any such bid (A) the Administrative Agent shall be authorized to form one or more acquisition vehicles to make a bid, (B) to adopt documents providing for the governance of the acquisition vehicle or vehicles (provided that any actions by the Administrative Agent with respect to such acquisition vehicle or vehicles, including any disposition of the assets or Equity Interests thereof shall be governed, directly or indirectly, by the vote of the Required Lenders, irrespective of the termination of this Agreement and without giving effect to the limitations on actions by the Required Lenders contained in Section 11.01), and (C) to the extent that Secured Obligations that are assigned to an acquisition vehicle are not used to acquire Collateral for any reason (as a result of another bid being higher or better, because the amount of Secured Obligations assigned to the acquisition vehicle exceeds the amount of debt credit bid by the acquisition vehicle or otherwise), such Secured Obligations shall automatically be reassigned to the Lenders pro rata and the Equity Interests and/or debt instruments issued by any acquisition vehicle on account of the Secured Obligations that had been assigned to the acquisition vehicle shall automatically be cancelled, without the need for any Secured Party or any acquisition vehicle to take any further action.

126 [Harmonic] Credit Agreement #231730035 9.10 Collateral and Guaranty Matters. (a) Each of the Lenders (including in its capacities as a potential Cash Management Bank and a potential Hedge Bank) and the L/C Issuer irrevocably authorize the Administrative Agent, (i) to release any Lien on any property granted to or held by the Administrative Agent under any Loan Document (i) upon the Facility Termination Date, (ii) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with any sale or other disposition permitted hereunder or under any other Loan Document, or (iii) if approved, authorized or ratified in writing by the requisite Lenders in accordance with Section 11.01; (ii) to subordinate any Lien on any property granted to or held by the Administrative Agent under any Loan Document to the holder of any Lien on such property that is permitted by Section 7.01(i) (as such section is in effect on the Closing Date); and (iii) to release any Guarantor from its obligations under the Guaranty if such Person ceases to be a Subsidiary as a result of a transaction permitted under the Loan Documents. (b) Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guaranty pursuant to this Section 9.10. In each case as specified in this Section 9.10, the Administrative Agent will, at the Borrower’s expense, execute and deliver to the applicable Loan Party such documents as such Loan Party may reasonably request to evidence the release of such item of Collateral from the assignment and security interest granted under the Collateral Documents or to subordinate its interest in such item, or to release such Guarantor from its obligations under the Guaranty, in each case in accordance with the terms of the Loan Documents and this Section 9.10. (c) The Administrative Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Administrative Agent’s Lien thereon, or any certificate prepared by any Loan Party in connection therewith, nor shall the Administrative Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral. 9.11 Secured Cash Management Agreements and Secured Hedge Agreements. Except as otherwise expressly set forth herein or in the Guaranty or any Collateral Document, no Cash Management Bank or Hedge Bank that obtains the benefit of the provisions of Section 8.03, the Guaranty or any Collateral by virtue of the provisions hereof or any Collateral Document shall have any right to notice of any action or to consent to, direct or object to any action hereunder or under any other Loan Document or otherwise in respect of the Collateral (including the release or impairment of any Collateral) (or to notice of or to consent to any amendment, waiver or modification of the provisions hereof or of the Guaranty or any Collateral Document) other than in its capacity as a Lender and, in such case, only to the extent expressly provided in the Loan Documents. Notwithstanding any other provision of this Article IX to the contrary, the Administrative Agent shall not be required to verify the payment of, or that other satisfactory arrangements have been made with respect to, Secured Obligations arising under Secured

127 [Harmonic] Credit Agreement #231730035 Cash Management Agreements and Secured Hedge Agreements except to the extent expressly provided herein and unless the Administrative Agent has received a Secured Party Designation Notice of such Secured Obligations, together with such supporting documentation as the Administrative Agent may request, from the applicable Cash Management Bank or Hedge Bank, as the case may be. The Administrative Agent shall not be required to verify the payment of, or that other satisfactory arrangements have been made with respect to, Secured Obligations arising under Secured Cash Management Agreements and Secured Hedge Agreements in the case of a Facility Termination Date. 9.12 Certain ERISA Matters. (a) Each Lender (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, the Administrative Agent and not, for the avoidance of doubt, to or for the benefit of the Borrower or any other Loan Party, that at least one of the following is and will be true: (i) such Lender is not using “plan assets” (within the meaning of Section 3(42) of ERISA or otherwise) of one or more Benefit Plans with respect to such Lender’s entrance into, participation in, administration of and performance of the Loans, the Letters of Credit, the Commitments, or this agreement, (ii) the transaction exemption set forth in one or more PTEs, such as PTE 84– 14 (a class exemption for certain transactions determined by independent qualified professional asset managers), PTE 95–60 (a class exemption for certain transactions involving insurance company general accounts), PTE 90–1 (a class exemption for certain transactions involving insurance company pooled separate accounts), PTE 91–38 (a class exemption for certain transactions involving bank collective investment funds) or PTE 96– 23 (a class exemption for certain transactions determined by in-house asset managers), is applicable with respect to such Lender’s entrance into, participation in, administration of and performance of the Loans, the Letters of Credit, the Commitments and this Agreement, or (iii) (A) such Lender is an investment fund managed by a “Qualified Professional Asset Manager” (within the meaning of Part VI of PTE 84–14), (B) such Qualified Professional Asset Manager made the investment decision on behalf of such Lender to enter into, participate in, administer and perform the Loans, the Letters of Credit, the Commitments and this Agreement, (C) the entrance into, participation in, administration of and performance of the Loans, the Letters of Credit, the Commitments and this Agreement satisfies the requirements of sub-sections (b) through (g) of Part I of PTE 84–14 and (D) to the best knowledge of such Lender, the requirements of subsection (a) of Part I of PTE 84–14 are satisfied with respect to such Lender’s entrance into, participation in, administration of and performance of the Loans, the Letters of Credit, the Commitments and this Agreement.

(a) If the Administrative Agent notifies a Lender, L/C Issuer or other Secured Party, or any Person who has received funds on behalf of a Lender, L/C Issuer or other Secured Party (any such Lender, L/C Issuer, Secured Party or other recipient, a “Payment Recipient”) that the Administrative Agent has determined in its sole discretion (whether or not after receipt of any notice under clause (b) of this Section) that any funds received by such Payment Recipient from the Administrative Agent or any of its Affiliates were erroneously transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Lender, L/C Issuer, Secured Party or other Payment Recipient on its behalf) (any such funds, whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an “Erroneous Payment”) and demands the return of such Erroneous Payment (or a portion thereof), such Erroneous Payment shall at all times remain the property of the Administrative Agent and shall be segregated by the Payment Recipient and held in trust for the benefit of the Administrative Agent, and such Lender, L/C Issuer or Secured Party shall (or, with respect to any Payment Recipient who received such funds on its behalf, shall cause such Payment Recipient to) promptly, but in no event later than two Business Days thereafter, return to the Administrative Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made, in same day funds (in the currency so received), together with interest thereon in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Administrative Agent in same day funds at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation from time to time in effect. A notice of the Administrative Agent to any Payment Recipient under this clause (a) shall be conclusive, absent manifest error. (b) Without limiting immediately preceding clause (a), each Payment Recipient hereby further agrees that if it receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise) from the Administrative Agent (or any of its Affiliates) (x) that is in a different amount than, or on a different date from, that specified in a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates), or (z) that such Payment Recipient otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part) in each case: (i) (A) in the case of immediately preceding clauses (x) or (y), an error shall be presumed to have been made (absent written confirmation from the Administrative Agent to the contrary) or (B) an error has been made (in the case of immediately preceding clause (z)), in each case, with respect to such payment, prepayment or repayment; and (ii) such Payment Recipient shall (and shall cause any other recipient that receives funds on its respective behalf to) promptly (and, in all events, within one Business Day of its knowledge of such error) notify the Administrative Agent of its receipt of such payment, prepayment or repayment, the details thereof (in reasonable detail) and that it is so notifying the Administrative Agent pursuant to this clause (b) of Section 9.13.

129 [Harmonic] Credit Agreement #231730035 (c) Each Lender, L/C Issuer or other Secured Party hereby authorizes the Administrative Agent to set off, net and apply any and all amounts at any time owing to such Lender, L/C Issuer or other Secured Party under any Loan Document, or otherwise payable or distributable by the Administrative Agent to such Lender, L/C Issuer or other Secured Party under any Loan Document, against any amount due to the Administrative Agent under clause (a) of Section 9.13 or under the indemnification provisions of this Agreement. (d) In the event that an Erroneous Payment (or portion thereof) is not recovered by the Administrative Agent for any reason, after demand therefor by the Administrative Agent in accordance with clause (a) of this Section, from any Lender or L/C Issuer that has received such Erroneous Payment (or portion thereof) (and/or from any Payment Recipient who received such Erroneous Payment (or portion thereof) on its respective behalf) (such unrecovered amount, an “Erroneous Payment Return Deficiency”), upon the Administrative Agent’s notice to such Lender or L/C Issuer at any time, (i) such Lender or L/C Issuer shall be deemed to have assigned its Loans (but not its Commitments) with respect to which such Erroneous Payment was made (the “Erroneous Payment Impacted Class”) in an amount equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Administrative Agent may specify) (such assignment of the Loans (but not Commitments) of the Erroneous Payment Impacted Class, the “Erroneous Payment Deficiency Assignment”) at par plus any accrued and unpaid interest (with the assignment fee to be waived by the Administrative Agent in such instance), and is hereby (together with the Borrower) deemed to execute and deliver an Assignment and Assumption (or, to the extent applicable, an agreement incorporating an Assignment and Assumption by reference pursuant to the Platform as to which the Administrative Agent and such parties are participants) with respect to such Erroneous Payment Deficiency Assignment, and such Lender or L/C Issuer shall deliver any Notes evidencing such Loans to the Borrower or the Administrative Agent, (ii) the Administrative Agent as the assignee Lender shall be deemed to acquire the Erroneous Payment Deficiency Assignment, (iii) upon such deemed acquisition, the Administrative Agent as the assignee Lender shall become a Lender or L/C Issuer, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Lender or assigning L/C Issuer shall cease to be a Lender or L/C Issuer, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment, excluding, for the avoidance of doubt, its obligations under the indemnification provisions of this Agreement and its applicable Commitments which shall survive as to such assigning Lender or assigning L/C Issuer and (iv) the Administrative Agent may reflect in the Register its ownership interest in the Loans subject to the Erroneous Payment Deficiency Assignment. The Administrative Agent may, in its discretion, sell any Loans acquired pursuant to an Erroneous Payment Deficiency Assignment and upon receipt of the proceeds of such sale, the Erroneous Payment Return Deficiency owing by the applicable Lender or L/C Issuer shall be reduced by the net proceeds of the sale of such Loan (or portion thereof), and the Administrative Agent shall retain all other rights, remedies and claims against such Lender or L/C Issuer (and/or against any recipient that receives funds on its respective behalf). For the avoidance of doubt, no Erroneous Payment Deficiency Assignment will reduce the Commitments of any Lender or L/C Issuer and such Commitments shall remain available in accordance with the terms of this Agreement. In addition, each party hereto agrees that, except to the extent that the Administrative Agent has sold a Loan (or portion thereof) acquired pursuant to an Erroneous Payment Deficiency Assignment, and irrespective of whether the Administrative Agent may be equitably subrogated, the Administrative Agent shall be contractually subrogated to all the rights and interests of the applicable Lender, L/C Issuer or other Secured Party under the Loan Documents with respect to each Erroneous Payment Return Deficiency (the “Erroneous Payment Subrogation Rights”). (e) The parties hereto agree that an Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any Obligations owed by the Borrower or any other Loan Party,

130 [Harmonic] Credit Agreement #231730035 except, in each case, to the extent such Erroneous Payment is, and solely with respect to the amount of such Erroneous Payment that is, comprised of funds received by the Administrative Agent from the Borrower or any other Loan Party for the purpose of making such Erroneous Payment. (f) To the extent permitted by applicable law, no Payment Recipient shall assert any right or claim to an Erroneous Payment, and hereby waives, and is deemed to waive, any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Administrative Agent for the return of any Erroneous Payment received, including without limitation waiver of any defense based on “discharge for value” or any similar doctrine. (g) Each party’s obligations, agreements and waivers under this Section 9.13 shall survive the resignation or replacement of the Administrative Agent, any transfer of rights or obligations by, or the replacement of, a Lender or L/C Issuer, the termination of the Commitments and/or the repayment, satisfaction or discharge of all Obligations (or any portion thereof) under any Loan Document. ARTICLE X CONTINUING GUARANTY 10.01 Guaranty. Each Guarantor hereby absolutely and unconditionally, jointly and severally guarantees, as primary obligor and as a guaranty of payment and performance and not merely as a guaranty of collection, prompt payment when due, whether at stated maturity, by required prepayment, upon acceleration, demand or otherwise, and at all times thereafter, of any and all Secured Obligations (for each Guarantor, subject to the proviso in this sentence, its “Guaranteed Obligations”); provided that (a) the Guaranteed Obligations of a Guarantor shall exclude any Excluded Swap Obligations with respect to such Guarantor and (b) the liability of each Guarantor individually with respect to this Guaranty shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance under Section 548 of the Bankruptcy Code of the United States or any comparable provisions of any applicable state law. Without limiting the generality of the foregoing, the Guaranteed Obligations shall include any such indebtedness, obligations, and liabilities, or portion thereof, which may be or hereafter become unenforceable or compromised or shall be an allowed or disallowed claim under any proceeding or case commenced by or against any debtor under any Debtor Relief Laws. The Administrative Agent’s books and records showing the amount of the Obligations shall be admissible in evidence in any action or proceeding, and shall be binding upon each Guarantor, and conclusive for the purpose of establishing the amount of the Secured Obligations. This Guaranty shall not be affected by the genuineness, validity, regularity or enforceability of the Secured Obligations or any instrument or agreement evidencing any Secured Obligations, or by the existence, validity, enforceability, perfection, non-perfection or extent of any collateral therefor, or by any fact or circumstance relating to the Secured Obligations which might otherwise constitute a defense to the obligations of the Guarantors, or any of them, under this Guaranty, and each Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to any or all of the foregoing. 10.02 Rights of Lenders. Each Guarantor consents and agrees that the Secured Parties may, at any time and from time to time, without notice or demand, and without affecting the enforceability or continuing effectiveness hereof: (a) amend, extend, renew, compromise, discharge, accelerate or otherwise change the time for payment or

131 [Harmonic] Credit Agreement #231730035 the terms of the Secured Obligations or any part thereof; (b) take, hold, exchange, enforce, waive, release, fail to perfect, sell, or otherwise dispose of any security for the payment of this Guaranty or any Secured Obligations; (c) apply such security and direct the order or manner of sale thereof as the Administrative Agent, the L/C Issuer and the Lenders in their sole discretion may determine; and (d) release or substitute one or more of any endorsers or other guarantors of any of the Secured Obligations. Without limiting the generality of the foregoing, each Guarantor consents to the taking of, or failure to take, any action which might in any manner or to any extent vary the risks of such Guarantor under this Guaranty or which, but for this provision, might operate as a discharge of such Guarantor. 10.03 Certain Waivers. Each Guarantor waives (a) any defense arising by reason of any disability or other defense of the Borrower or any other guarantor, or the cessation from any cause whatsoever (including any act or omission of any Secured Party) of the liability of the Borrower or any other Loan Party; (b) any defense based on any claim that such Guarantor’s obligations exceed or are more burdensome than those of the Borrower or any other Loan Party; (c) the benefit of any statute of limitations affecting any Guarantor’s liability hereunder; (d) any right to proceed against the Borrower or any other Loan Party, proceed against or exhaust any security for the Secured Obligations, or pursue any other remedy in the power of any Secured Party whatsoever; (e) any benefit of and any right to participate in any security now or hereafter held by any Secured Party; and (f) to the fullest extent permitted by law, any and all other defenses or benefits that may be derived from or afforded by Applicable Law limiting the liability of or exonerating guarantors or sureties. Each Guarantor expressly waives all setoffs and counterclaims and all presentments, demands for payment or performance, notices of nonpayment or nonperformance, protests, notices of protest, notices of dishonor and all other notices or demands of any kind or nature whatsoever with respect to the Secured Obligations, and all notices of acceptance of this Guaranty or of the existence, creation or incurrence of new or additional Secured Obligations. 10.04 Obligations Independent. The obligations of each Guarantor hereunder are those of primary obligor, and not merely as surety, and are independent of the Secured Obligations and the obligations of any other guarantor, and a separate action may be brought against each Guarantor to enforce this Guaranty whether or not the Borrower or any other person or entity is joined as a party. 10.05 Subrogation. No Guarantor shall exercise any right of subrogation, contribution, indemnity, reimbursement or similar rights with respect to any payments it makes under this Guaranty until all of the Secured Obligations and any amounts payable under this Guaranty have been indefeasibly paid and performed in full (other than contingent indemnification obligations) and the Commitments and the Facilities are terminated. If any amounts are paid to a Guarantor in violation of the foregoing limitation, then such amounts shall be held in trust for the benefit of the Secured Parties and shall forthwith be paid to the Secured Parties to reduce the amount of the Secured Obligations, whether matured or unmatured. 10.06 Termination; Reinstatement. This Guaranty is a continuing and irrevocable guaranty of all Secured Obligations now or hereafter existing and shall remain in full force and effect until the Facility Termination Date. Notwithstanding the foregoing, this Guaranty shall continue in full force and effect or be revived, as the case may be, if any payment by or on behalf of the Borrower or a Guarantor is made, or any of the Secured Parties exercises its right of setoff, in respect of the Secured Obligations and such payment or the proceeds of such setoff or

132 [Harmonic] Credit Agreement #231730035 any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by any of the Secured Parties in their discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Laws or otherwise, all as if such payment had not been made or such setoff had not occurred and whether or not the Secured Parties are in possession of or have released this Guaranty and regardless of any prior revocation, rescission, termination or reduction. The obligations of each Guarantor under this Section 10.06 shall survive termination of this Guaranty. 10.07 Stay of Acceleration. If acceleration of the time for payment of any of the Secured Obligations is stayed, in connection with any case commenced by or against a Guarantor or the Borrower under any Debtor Relief Laws, or otherwise, all such amounts shall nonetheless be payable by each Guarantor, jointly and severally, immediately upon demand by the Secured Parties. 10.08 Condition of Borrower. Each Guarantor acknowledges and agrees that it has the sole responsibility for, and has adequate means of, obtaining from the Borrower and any other guarantor such information concerning the financial condition, business and operations of the Borrower and any such other guarantor as such Guarantor requires, and that none of the Secured Parties has any duty, and such Guarantor is not relying on the Secured Parties at any time, to disclose to it any information relating to the business, operations or financial condition of the Borrower or any other guarantor (each Guarantor waiving any duty on the part of the Secured Parties to disclose such information and any defense relating to the failure to provide the same). 10.09 Appointment of Borrower. Each of the Loan Parties hereby appoints the Borrower to act as its agent for all purposes of this Agreement, the other Loan Documents and all other documents and electronic platforms entered into in connection herewith and agrees that (a) the Borrower may execute such documents and provide such authorizations on behalf of such Loan Parties as the Borrower deems appropriate in its sole discretion and each Loan Party shall be obligated by all of the terms of any such document and/or authorization executed on its behalf, (b) any notice or communication delivered by the Administrative Agent, L/C Issuer or a Lender to the Borrower shall be deemed delivered to each Loan Party and (c) the Administrative Agent, L/C Issuer or the Lenders may accept, and be permitted to rely on, any document, authorization, instrument or agreement executed by the Borrower on behalf of each of the Loan Parties. 10.10 Right of Contribution. The Guarantors agree among themselves that, in connection with payments made hereunder, each Guarantor shall have contribution rights against the other Guarantors as permitted under Applicable Law. 10.11 Keepwell. Each Loan Party that is a Qualified ECP Guarantor at the time the Guaranty or the grant of a Lien under the Loan Documents, in each case, by any Specified Loan Party becomes effective with respect to any Swap Obligation, hereby jointly and severally, absolutely, unconditionally and irrevocably undertakes to provide such funds or other support to each Specified Loan Party with respect to such Swap Obligation as may be needed by such Specified Loan Party from time to time to honor all of its obligations under the Loan Documents in respect of such Swap Obligation (but, in each case, only up to the maximum amount of such liability that can be hereby incurred without rendering such Qualified ECP Guarantor’s obligations

133 [Harmonic] Credit Agreement #231730035 and undertakings under this Article X voidable under Applicable Law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations and undertakings of each Qualified ECP Guarantor under this Section 10.11 shall remain in full force and effect until the Secured Obligations have been indefeasibly paid and performed in full (other than contingent indemnification obligations). Each Loan Party intends this Section 10.11 to constitute, and this Section 10.11 shall be deemed to constitute, a guarantee of the obligations of, and a “keepwell, support, or other agreement” for the benefit of, each Specified Loan Party for all purposes of the Commodity Exchange Act. ARTICLE XI MISCELLANEOUS 11.01 Amendments, Etc. (a) Subject to Section 3.03 and the last paragraph of this Section 11.01, no amendment or waiver of any provision of this Agreement or any other Loan Document, and no consent to any departure by the Borrower or any other Loan Party therefrom, shall be effective unless in writing signed by the Required Lenders (or by the Administrative Agent with the consent of the Required Lenders) and the Borrower or the applicable Loan Party, as the case may be, and acknowledged by the Administrative Agent, and each such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided that no such amendment, waiver or consent shall: (i) waive any condition set forth in Section 4.01, or, in the case of the initial Credit Extension, Section 4.02, without the written consent of each Lender; (ii) extend or increase the Commitment of any Lender (or reinstate any Commitment terminated pursuant to Section 8.02) without the written consent of such Lender (it being understood and agreed that a waiver of any condition precedent in Section 4.02 or of any Default or a mandatory reduction in Commitments is not considered an extension or increase in Commitments of any Lender); (iii) postpone any date fixed by this Agreement or any other Loan Document for any payment (excluding mandatory prepayments) of principal, interest, fees or other amounts due to the Lenders (or any of them) or reduce the amount of, waive or excuse any such payment hereunder or under such other Loan Document without the written consent of each Lender entitled to such payment; (iv) reduce the principal of, or the rate of interest specified herein on, any Loan or L/C Borrowing, or (subject to clause (D) of the second proviso to this Section 11.01) any fees or other amounts payable hereunder or under any other Loan Document, without the written consent of each Lender entitled to such amount; provided that only the consent of the Required Lenders shall be necessary (i) to amend the definition of “Default Rate” or to waive any obligation of the Borrower to pay interest or Letter of Credit Fees at the Default Rate or (ii) to amend any financial covenant hereunder (or any defined term used therein) even if the effect of such amendment would be to reduce the rate of interest on any Loan or L/C Borrowing or to reduce any fee payable hereunder; (v) change (i) Section 8.03 or Section 2.13 in a manner that would have the effect of altering the ratable reduction of Commitments, pro rata payments or pro rata sharing of payments (or, in the case of Section 8.03, the order of application of payments)

134 [Harmonic] Credit Agreement #231730035 required hereunder without the written consent of each Lender, (ii) Section 2.12(f) in a manner that would alter the pro rata application required thereby without the written consent of each Lender directly affected thereby or (iii) subordinate, or have the effect of subordinating, the Obligations hereunder to any other Indebtedness or other obligation, in each case, without the written consent of each Lender; (vi) change any provision of this Section 11.01 or the definition of “Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders required to amend, waive or otherwise modify any rights hereunder or thereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; (vii) release all or substantially all of the Collateral in any transaction or series of related transactions, without the written consent of each Lender; (viii) release, or have the effect of releasing, all or substantially all of the value of the Guaranty, without the written consent of each Lender, except to the extent the release of any Subsidiary from the Guaranty is permitted pursuant to Section 9.10 (in which case such release may be made by the Administrative Agent acting alone); or (ix) release the Company (from its obligations as a Borrower or as a Guarantor hereunder) or any Designated Borrower, except in connection with the termination of a Designated Borrower’s status as such under Section 2.17, a merger or consolidation permitted under Section 7.04 or a Disposition permitted under Section 7.05; and provided further that (A) no amendment, waiver or consent shall, unless in writing and signed by the L/C Issuer in addition to the Lenders required above, affect the rights or duties of the L/C Issuer under this Agreement or any Issuer Document relating to any Letter of Credit issued or to be issued by it; (B) no amendment, waiver or consent shall, unless in writing and signed by the Swingline Lender in addition to the Lenders required above, affect the rights or duties of the Swingline Lender under this Agreement; (C) no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent in addition to the Lenders required above, affect the rights or duties of the Administrative Agent under this Agreement or any other Loan Document; and (D) the Fee Letter may be amended, or rights or privileges thereunder waived, in a writing executed only by the parties thereto. (b) Notwithstanding anything to the contrary herein, (i) no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment, waiver or consent which by its terms requires the consent of all Lenders or each affected Lender, or all Lenders or each affected Lender under a Facility, may be effected with the consent of the applicable Lenders other than Defaulting Lenders), except that (A) the Commitment of any Defaulting Lender may not be increased or extended without the consent of such Lender and (B) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender, or all Lenders or each affected Lender under a Facility, that by its terms affects any Defaulting Lender disproportionately adversely relative to other affected Lenders shall require the consent of such Defaulting Lender; (ii) each Lender is entitled to vote as such Lender sees fit on any bankruptcy reorganization plan that affects the Loans, and each Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy Code of the United States supersedes the unanimous consent provisions set forth herein and (iii) the Required Lenders shall determine whether or not to allow a Loan Party to use cash collateral in the context of a bankruptcy or insolvency proceeding and such determination shall be binding on all of the Lenders.

(a) No failure by any Lender, the L/C Issuer or the Administrative Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or under any other Loan Document preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

Without limiting the provisions of Section 3.01(c), this Section 11.04(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment under any Facility and/or the Loans at the time owing to it (in each case with respect to any Facility) or contemporaneous assignments to related Approved Funds (determined after giving effect to such

141 [Harmonic] Credit Agreement #231730035 assignments) that equal at least the amount specified in clause (b)(i)(B) of this Section 11.06 in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and (B) in any case not described in clause (b)(i)(A) of this Section 11.06, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $5,000,000 in the case of any assignment in respect of the Revolving Facility, or $5,000,000, in the case of any assignment in respect of the Term Facility, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed). (ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement and the other Loan Documents with respect to the Loans and/or the Commitment assigned, except that this clause (b)(ii) shall not apply to the Swingline Lender’s rights and obligations in respect of Swingline Loans. (iii) Required Consents. No consent shall be required for any assignment except to the extent required by clause (b)(i)(B) of this Section 11.06 and, in addition: (A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (1) an Event of Default has occurred and is continuing at the time of such assignment or (2) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof; and provided further that the Borrower’s consent shall not be required during the primary syndication of the Facilities; (B) (B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments in respect of (1) any unfunded Term Commitment or any Revolving Commitment if such assignment is to a Person that is not a Lender with a Commitment in respect of the applicable Facility, an Affiliate of such Lender or an Approved Fund with respect to such Lender or (2) any Term Loan to a Person that is not a Lender, an Affiliate of a Lender or an Approved Fund; and (C) the consent of the L/C Issuer and the Swingline Lender shall be required for any assignment in respect of the Revolving Facility.

The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee in the amount of $3,500; provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the

142 [Harmonic] Credit Agreement #231730035 case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. (v) No Assignment to Certain Persons. No such assignment shall be made (A) to the Borrower or any of the Borrower’s Affiliates or Subsidiaries, (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B), or (C) to a natural Person (or a holding company, investment vehicle or trust for, or owned and operated by or for the primary benefit of one or more natural Persons). (vi) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or sub-participations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (A) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the L/C Issuer or any Lender hereunder (and interest accrued thereon) and (B) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit and Swingline Loans in accordance with its Applicable Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under Applicable Law without compliance with the provisions of this clause (b)(vi), then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs. (vii) Subject to acceptance and recording thereof by the Administrative Agent pursuant to Section 11.06(c), from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 3.01, 3.04, 3.05 and 11.04 with respect to facts and circumstances occurring prior to the effective date of such assignment); provided that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender; provided further that the assignee thereunder shall not be entitled to receive any greater payment under Sections 3.01 or 3.04, with respect to the interest assigned by such Assignment and Assumption, than the assigning Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after such assignment. Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this clause (b) shall be treated for purposes of this

143 [Harmonic] Credit Agreement #231730035 Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 11.06(d). (c) Register. The Administrative Agent, acting solely for this purpose as a non- fiduciary agent of the Borrower (and such agency being solely for Tax purposes), shall maintain at the Administrative Agent’s Office a copy of each Assignment and Assumption delivered to it (or the equivalent thereof in electronic form) and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and interest amounts) of the Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and any Lender (with respect to such Lender’s interest only), at any reasonable time and from time to time upon reasonable prior notice. (d) Participations. (i) Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural Person, or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of one or more natural Persons, a Defaulting Lender or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender’s participations in L/C Obligations and/or Swingline Loans) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, the Lenders and the L/C Issuer shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 11.04(c) without regard to the existence of any participations. (ii) Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso to Section 11.01 that affects such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 (subject to the requirements and limitations therein, including the requirements under Section 3.01(e) (it being understood that the documentation required under Section 3.01(e) shall be delivered to the Lender who sells the participation)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to clause (b) of this Section 11.06; provided that such Participant (A) shall be subject to the provisions of Sections 3.06 and 11.13 as if it were an assignee under clause (b) of this Section 11.06 and (B) shall not be entitled to receive any greater payment under Sections 3.01 or 3.04, with respect to any participation, than the Lender from whom it acquired the applicable participation would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the

144 [Harmonic] Credit Agreement #231730035 Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 3.06 with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.08 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.13 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and interest amounts) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103–1(c) of the United States Treasury Regulations (or any successor provision thereof). The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register. (e) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Note or Notes, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. (f) Resignation as L/C Issuer or Swingline Lender after Assignment. Notwithstanding anything to the contrary contained herein, if at any time Citibank assigns all of its Revolving Commitment and Revolving Loans pursuant to clause (b) above, Citibank may, (i) upon thirty (30) days’ notice to the Administrative Agent, the Borrower and the Lenders, resign as L/C Issuer and/or (ii) upon thirty (30) days’ notice to the Borrower, resign as Swingline Lender. In the event of any such resignation as L/C Issuer or Swingline Lender, the Borrower shall be entitled to appoint from among the Lenders a successor L/C Issuer or Swingline Lender hereunder; provided that no failure by the Borrower to appoint any such successor shall affect the resignation of Citibank as L/C Issuer or Swingline Lender, as the case may be. If Citibank resigns as L/C Issuer, it shall retain all the rights, powers, privileges and duties of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as L/C Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.03(c)). If Citibank resigns as Swingline Lender, it shall retain all the rights of the Swingline Lender provided for hereunder with respect to Swingline Loans made by it and outstanding as of the effective date of such resignation, including the right to require the Lenders to make Base Rate Loans or fund risk participations in outstanding Swingline Loans pursuant to Section 2.04(c). Upon the appointment of a successor L/C Issuer and/or Swingline Lender, (A) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer or Swingline Lender, as the case may be, and (B) the successor L/C Issuer shall issue letters of credit in substitution for the Letters

145 [Harmonic] Credit Agreement #231730035 of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to Citibank to effectively assume the obligations of Citibank with respect to such Letters of Credit. 11.07 Treatment of Certain Information; Confidentiality.

Each Lender and the L/C Issuer agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application. 11.09 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by Applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by Applicable Law, (a) characterize any

147 [Harmonic] Credit Agreement #231730035 payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder. 11.10 Integration; Effectiveness. This Agreement, the other Loan Documents, and any separate letter agreements with respect to fees payable to the Administrative Agent or the L/C Issuer, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successor and assigns. 11.11 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of any Credit Extension, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding. 11.12 Severability. If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 11.12, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by Debtor Relief Laws, as determined in good faith by the Administrative Agent, the L/C Issuer or the Swingline Lender, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited. 11.13 Replacement of Lenders. (a) If the Borrower is entitled to replace a Lender pursuant to the provisions of Section 3.06, or if any Lender is a Defaulting Lender or a Non-Consenting Lender or if any other circumstance exists hereunder that gives the Borrower the right to replace a Lender as a party hereto, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 11.06), all of its interests, rights (other than its existing rights to payments pursuant to Sections 3.01 and 3.04) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that

148 [Harmonic] Credit Agreement #231730035 shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that: (i) the Borrower shall have paid (or caused a Designated Borrower to pay) to the Administrative Agent the assignment fee (if any) specified in Section 11.06(b); (ii) such Lender shall have received payment of an amount equal to 100% of the outstanding principal of its Loans and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.05) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower or applicable Designated Borrower (in the case of all other amounts); (iii) in the case of any such assignment resulting from a claim for compensation under Section 3.04 or payments required to be made pursuant to Section 3.01, such assignment will result in a reduction in such compensation or payments thereafter; (iv) such assignment does not conflict with Applicable Laws; and (v) in the case of an assignment resulting from a Lender becoming a Non- Consenting Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent. (b) A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. (c) Each party hereto agrees that (i) an assignment required pursuant to this Section 11.13 may be effected pursuant to an Assignment and Assumption executed by the Borrower, the Administrative Agent and the assignee and (ii) the Lender required to make such assignment need not be a party thereto in order for such assignment to be effective and shall be deemed to have consented to an be bound by the terms thereof; provided that following the effectiveness of any such assignment, the other parties to such assignment agree to execute and deliver such documents necessary to evidence such assignment as reasonably requested by the applicable Lender, provided further that any such documents shall be without recourse to or warranty by the parties thereto. (d) Notwithstanding anything in this Section 11.13 to the contrary, (A) the Lender that acts as the L/C Issuer may not be replaced hereunder at any time it has any Letter of Credit outstanding hereunder unless arrangements satisfactory to such Lender (including the furnishing of a backstop standby letter of credit in form and substance, and issued by an issuer, reasonably satisfactory to the L/C Issuer or the depositing of Cash Collateral into a Cash Collateral account in amounts and pursuant to arrangements reasonably satisfactory to the L/C Issuer) have been made with respect to such outstanding Letter of Credit and (B) the Lender that acts as the Administrative Agent may not be replaced hereunder except in accordance with the terms of Section 9.06. 11.14 Governing Law; Jurisdiction; Etc. (a) GOVERNING LAW.

(c) WAIVER OF VENUE. THE BORROWER AND EACH OTHER LOAN PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT IN ANY COURT REFERRED TO IN CLAUSE (b) OF THIS SECTION 11.14.

Each Loan Party (a “Subordinating Loan Party”) hereby subordinates the payment of all obligations and indebtedness of any other Loan Party owing to it, whether now existing or hereafter arising, including but not limited to any obligation of any such other Loan Party to the Subordinating Loan Party as subrogee of the Secured Parties or resulting from such Subordinating Loan Party’s performance under this Guaranty, to the indefeasible payment in full in cash of all Obligations. If the Secured Parties so request, any such obligation or indebtedness of any such other Loan Party to the Subordinating Loan Party shall be enforced and performance received by the Subordinating Loan Party as trustee for the Secured Parties and the proceeds thereof shall be paid over to the Secured Parties on account of the Secured Obligations, but without reducing or affecting in any manner the liability of the Subordinating Loan Party under this Agreement. Without limitation of the foregoing, so long as no Default has occurred and is continuing, the Loan Parties may make and receive payments with respect to Intercompany Debt; provided that in the event that any Loan Party receives any payment of any Intercompany Debt at a time when such payment is prohibited by this Section 11.16, such payment shall be held by such Loan Party, in trust for the benefit of, and shall be paid forthwith over and delivered, upon written request, to the Administrative Agent. 11.17 No Advisory or Fiduciary Responsibility. In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document), the Borrower and each other Loan Party acknowledges and agrees, and acknowledges its Affiliates’ understanding, that: (a) (i) the arranging and other services regarding this Agreement provided by the Administrative Agent, the Arranger and the Lenders and their respective Affiliates are arm’s-length commercial transactions between the Borrower, each other Loan Party and their respective Affiliates, on the one hand, and the Administrative Agent, the Arranger and the Lenders and their respective Affiliates, on the other hand, (ii) each of the Borrower and the other Loan Parties has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate, and (iii) the Borrower and each other Loan Party is capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents; (b) (i) the Administrative Agent, the Arranger and each Lender and each of their respective Affiliates each is and has been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary, for the Borrower, any other Loan Party or any of their respective Affiliates, or any other Person and (ii) neither the Administrative Agent, the Arranger, nor any Lender nor any of their respective Affiliates has any obligation to the Borrower, any other Loan Party or any of their respective Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in

151 [Harmonic] Credit Agreement #231730035 the other Loan Documents; and (c) the Administrative Agent, the Arranger and the Lenders and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower, the other Loan Parties and their respective Affiliates, and neither the Administrative Agent, the Arranger, nor any Lender nor any of their respective Affiliates has any obligation to disclose any of such interests to the Borrower, any other Loan Party or any of their respective Affiliates. To the fullest extent permitted by law, each of the Borrower and each other Loan Party hereby waives and releases any claims that it may have against the Administrative Agent, the Arranger, the Lenders and their respective Affiliates with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transactions contemplated hereby. 11.18 Electronic Execution; Electronic Records; Counterparts. This Agreement, any Loan Document and any other Communication, including Communications required to be in writing, may be in the form of an Electronic Record and may be executed using Electronic Signatures. Each of the Loan Parties and each of the Administrative Agent, the L/C Issuer, the Swingline Lender, and each Lender (collectively, each a “Credit Party”) agrees that any Electronic Signature on or associated with any Communication shall be valid and binding on such Person to the same extent as a manual, original signature, and that any Communication entered into by Electronic Signature, will constitute the legal, valid and binding obligation of such Person enforceable against such Person in accordance with the terms thereof to the same extent as if a manually executed original signature was delivered. Any Communication may be executed in as many counterparts as necessary or convenient, including both paper and electronic counterparts, but all such counterparts are one and the same Communication. For the avoidance of doubt, the authorization under this paragraph may include, without limitation, use or acceptance of a manually signed paper Communication which has been converted into electronic form (such as scanned into PDF format), or an electronically signed Communication converted into another format, for transmission, delivery and/or retention. The Administrative Agent and each of the Credit Parties may, at its option, create one or more copies of any Communication in the form of an imaged Electronic Record (“Electronic Copy”), which shall be deemed created in the ordinary course of such Person’s business, and destroy the original paper document. All Communications in the form of an Electronic Record, including an Electronic Copy, shall be considered an original for all purposes, and shall have the same legal effect, validity and enforceability as a paper record. Notwithstanding anything contained herein to the contrary, neither the Administrative Agent, L/C Issuer nor Swingline Lender is under any obligation to accept an Electronic Signature in any form or in any format unless expressly agreed to by such Person pursuant to procedures approved by it; provided that, without limiting the foregoing, (a) to the extent the Administrative Agent, L/C Issuer and/or Swingline Lender has agreed to accept such Electronic Signature, the Administrative Agent and each of the Credit Parties shall be entitled to rely on any such Electronic Signature purportedly given by or on behalf of any Loan Party and/or any Credit Party without further verification and (b) upon the request of the Administrative Agent or any Credit Party, any Electronic Signature shall be promptly followed by such manually executed counterpart. For purposes hereof, “Electronic Record” and “Electronic Signature” shall have the meanings assigned to them, respectively, by 15 USC §7006, as it may be amended from time to time. Neither the Administrative Agent, L/C Issuer nor Swingline Lender shall be responsible for or have any duty to ascertain or inquire into the sufficiency, validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document (including, for the avoidance of doubt, in connection with the Administrative Agent’s, L/C Issuer’s or Swingline Lender’s reliance on any Electronic Signature transmitted by telecopy, emailed .pdf or any other electronic means). The Administrative Agent, L/C Issuer and Swingline Lender shall be entitled to rely on, and shall incur no liability under or in respect of this Agreement or any other Loan Document by acting upon, any Communication (which writing may be a fax, any electronic message, Internet or intranet website posting or other distribution or signed using an Electronic Signature) or any statement made to it orally or by

152 [Harmonic] Credit Agreement #231730035 telephone and believed by it to be genuine and signed or sent or otherwise authenticated (whether or not such Person in fact meets the requirements set forth in the Loan Documents for being the maker thereof). Each of the Loan Parties and each Credit Party hereby waives (i) any argument, defense or right to contest the legal effect, validity or enforceability of this Agreement and/or any other Loan Document based solely on the lack of paper original copies of this Agreement and/or such other Loan Document, and (ii) waives any claim against the Administrative Agent, each Credit Party and each Related Party for any liabilities arising solely from the Administrative Agent’s and/or any Credit Party’s reliance on or use of Electronic Signatures, including any liabilities arising as a result of the failure of the Loan Parties to use any available security measures in connection with the execution, delivery or transmission of any Electronic Signature. 11.19 USA Patriot Act Notice. Each Lender that is subject to the Patriot Act and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower and the other Loan Parties that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107–56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower and each other Loan Party, which information includes the name and address of the Borrower and each other Loan Party and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower and each other Loan Party in accordance with the Patriot Act. The Borrower and each other Loan Party shall, promptly following a request by the Administrative Agent or any Lender, provide all such other documentation and information that the Administrative Agent or such Lender requests in order to comply with its ongoing obligations under applicable “know your customer” and anti- money laundering rules and regulations, including the Patriot Act. 11.20 Acknowledgement and Consent to Bail-In of Affected Financial Institutions. Solely to the extent any Lender or L/C Issuer that is an Affected Financial Institution is a party to this Agreement and notwithstanding anything to the contrary in any Loan Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any Lender or L/C Issuer that is an Affected Financial Institution arising under any Loan Document, to the extent such liability is unsecured, may be subject to the Write-Down and Conversion Powers of an applicable Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by: (a) the application of any Write-Down and Conversion Powers by the applicable Resolution Authority to any such liabilities arising hereunder which may be payable to it by any Lender or L/C Issuer that is an Affected Financial Institution; and (b) the effects of any Bail-In Action on any such liability, including, if applicable: (i) a reduction in full or in part or cancellation of any such liability; (ii) a conversion of all, or a portion of, such liability into shares or other instruments of ownership in such Affected Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Loan Document; or

153 [Harmonic] Credit Agreement #231730035 (iii) the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion Powers of the applicable Resolution Authority. 11.21 Acknowledgement Regarding Any Supported QFCs. To the extent that the Loan Documents provide support, through a guarantee or otherwise, for any Swap Contract or any other agreement or instrument that is a QFC (such support, “QFC Credit Support”, and each such QFC, a “Supported QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States): In the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.

Recitals: A. The Lenders have agreed to provide the Company with certain loan facilities and other financial accommodations (the “Loan Facilities”) under the terms and conditions of the Credit Agreement, which Loan Facilities are guaranteed by the Guarantors. The Loan Parties have secured the repayment of the Loan Facilities and certain other obligations (collectively, defined as “Secured Obligations” in the Credit Agreement) by granting the Administrative Agent, for the ratable benefit of the Secured Parties (as defined in the Credit Agreement), a security interest in all of the Loan Parties’ personal property, whether now owned or hereafter acquired, including all proceeds of any of the foregoing (collectively, the “Collateral”). B. Whereas Landlord is the lessor under the lease described in Exhibit A attached hereto (the “Lease”) with [_________________] (the “Tenant”) as lessee pursuant to which Landlord has leased certain premises to Tenant located at [____________________] (the “Premises”). C. As a condition to extending the Loan Facilities, the Lenders and the Administrative Agent have requested that the Loan Parties obtain, and cause the Landlord to provide, a waiver and subordination, pursuant to the terms of this Agreement, of all of its rights against any of the Collateral until the Facility Termination Date (as defined in the Credit Agreement).

Landlord hereby subordinates in favor of the Administrative Agent, for the benefit of the Secured Parties, any and all rights or interests that Landlord, or its successors and assigns, may now or

-5- [Harmonic] Exhibits to Credit Agreement #234055822 hereafter have in or to the Collateral, including, without limitation, any lien, claim, charge or encumbrance of any kind or nature, arising by statute, contract, common law or otherwise. 2. Landlord hereby agrees that the liens and security interests existing in favor of the Administrative Agent, for the ratable benefit of the Secured Parties, shall be prior and superior to (a) any and all rights of distraint, levy, and execution which Landlord may now or hereafter have against the Collateral, (b) any and all liens and security interests which Landlord may now or hereafter have on and in the Collateral, and (c) any and all other rights, demands and claims of every nature whatsoever which Landlord may now or hereafter have on or against the Collateral for any reason whatsoever, including, without limitation, rent, storage charge, or similar expense, cost or sum due or to become due Landlord by Tenant under the provisions of any lease, storage agreement or otherwise, and Landlord hereby subordinates all of its foregoing rights and interests in the Collateral to the security interest of the Administrative Agent in the Collateral. Landlord deems the Collateral to be personal property, not fixtures. 3. Upon the advance written notice from the Administrative Agent that an event of default has occurred and is continuing under the Credit Agreement, Landlord agrees that the Administrative Agent or its delegates or assigns may enter upon the Premises at any time or times, during normal business hours, to inspect or remove the Collateral, or any part thereof, from the Premises, without charge, either prior to or subsequent to the termination of the Lease, provided that in any event such removal shall occur no later than forty-five (45) days after the termination of the Lease. The Administrative Agent shall repair or pay reasonable compensation to Landlord for damage, if any, to the Premises caused by the removal of the Collateral. In addition to the above removal rights, the Landlord will permit the Administrative Agent to remain on the Premises for forty-five (45) days after the Administrative Agent gives the Landlord notice of its intention to do so and to take such action as the Administrative Agent deems necessary or appropriate in order to liquidate the Collateral, provided that the Administrative Agent shall pay to the Landlord the basic rent due under the Lease pro-rated on a per diem basis determined on a 30-day month (provided, that such rent shall exclude any rent adjustments, indemnity payments or similar amounts payable under the Lease for default, holdover status or similar charges). 4. Landlord represents and warrants: (a) that it has not assigned its claims for payment, if any, nor its right to perfect or assert a lien of any kind whatsoever against Tenant’s Collateral; (b) that it has the right, power and authority to execute this Agreement; (c) that it holds legal title to the Premises; (d) that it is not aware of any breach or default by the Tenant of its obligations under the Lease with respect to the Premises; and (e) the Lease, together with all assignments, modifications, supplementations and amendments set forth in Exhibit A, represents, as of the date hereof, the entire agreement between the parties with respect to the lease of the Premises. Landlord further agrees to provide the Administrative Agent with prompt written notice in the event that Landlord sells the Premises or any portion thereof. 5. The Landlord shall send to the Administrative Agent (in the manner provided herein) a copy of any notice or statement sent to the Tenant by the Landlord asserting a default under the Lease. Such copy shall be sent to the Administrative Agent at the same time such notice or statement is sent to the Tenant.
