Β 
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 Xxxxxx’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.

(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 Xxxxxx’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

Β 
50 [Harmonic] Credit Agreement #231730035 such Xxxxxx’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 β€œUnreimbursed 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;

(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;

Β 
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 Xxxxxxxx’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.

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.

(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 β€œLetter 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

Β 
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.

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).

Β 
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 β€œL/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 β€œCollateral 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

Β 
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.

Β 
56 [Harmonic] Credit Agreement #231730035 its sole discretion make loans to the Borrower (each such loan, a β€œSwingline 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

Β 
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.

Β 
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

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).

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.

(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.

(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.

Β 
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,

Β 
64 [Harmonic] Credit Agreement #231730035 a funding fee (the β€œFunding 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 Xxxxxx and the Register, the Register shall control in the absence of manifest error. Upon the request of any Xxxxxx made through the Administrative Agent, the Borrower shall execute and deliver to such Lender (through the Administrative Agent) a Note, which shall evidence such

Β 
65 [Harmonic] Credit Agreement #231730035 Xxxxxx’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 Xxxxxx’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 Xxxxxxx; 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

Β 
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 β€œRescindable 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 Xxxxxx 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

Β 
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 Xxxxxxx. 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

Β 
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

Β 
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 Xxxxxx’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 β€œRequired 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

Β 
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 Xxxxxx having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Xxxxxx’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

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).

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.

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.

(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

Β 
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:

Β 
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 β€œScheduled Unavailability Date”); then, on a date and time determined by the Administrative Agent (any such date, the β€œTerm 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 β€œSuccessor 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 β€œSuccessor 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.

Β

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

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.

Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee Lender.

Β 
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 β€œRegister”). 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 Xxxxxx’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 β€œParticipant”) 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

Β 
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 β€œParticipant 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.

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).

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.
