     This Second Amended and Restated Loan and Security Agreement (as amended, restated, or otherwise modified from time to time, this “Agreement”), dated as of December 17, 2004, is by and between Silicon Valley Bank (“Bank”), whose address is 3003 Tasman Drive, Santa Clara, California, 95054, and Harmonic Inc., a Delaware corporation (“Borrower”), whose address is 549 Baltic Way, Sunnyvale, California 94089, and provides the terms on which Bank will lend to Borrower and Borrower will repay Bank. This Agreement amends and restates in its entirety that certain Amended and Restated Loan and Security Agreement, dated December 19, 2003. The parties hereto agree as follows:

1. Definitions; Accounting and Other Terms

     Capitalized terms used herein shall have the meanings given to such terms in Section 13 of this Agreement. Accounting terms not defined in this Agreement will be construed according to GAAP. Calculations and determinations must be made following GAAP. The term “financial statements” includes the notes and schedules thereto. The terms “including” and “includes” always mean “including (or includes) without limitation,” in this or any other Loan Document.

2. Loan And Terms Of Payment

     2.1 Promise to Pay.

     Borrower promises to pay Bank the unpaid principal amount of all Advances and interest on the unpaid principal amount of the Advances.

          2.1.1 Advances.

                    (a) Bank will make Advances not exceeding the Committed Revolving Line minus (a) the outstanding principal balance of the Advances minus (b) the amount of all outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit). Amounts borrowed hereunder that remain available for borrowing under this Agreement may be repaid and reborrowed prior to the Maturity Date.

                    (b) To obtain an Advance, Borrower must notify Bank by facsimile or telephone by 12:00 noon Pacific Time on the Business Day the Advance is to be made. Borrower must promptly confirm the notification by delivering to Bank the Loan Payment/Advance Request Form attached as Exhibit B (the “Payment/Advance Form”). Bank will credit Advances to Borrower’s deposit account. Bank may make Advances under this Agreement based on instructions from a Responsible Officer or his or her designee or without instructions if the Advances are necessary to meet Obligations which have become due. Bank may rely on any telephone notice given by a person whom Bank believes is a Responsible Officer or designee. Borrower will indemnify Bank for any loss Bank suffers due to such reliance.

                    (c) The Committed Revolving Line shall terminate on the Maturity Date, and all Advances are immediately due and payable on the Maturity Date.

          2.1.2 Letters of Credit.

               (a) Bank will issue or have issued standby Letters of Credit for Borrower’s account not exceeding the amount available under the Committed Revolving Line (each, a “Letter of Credit”). Each Letter of Credit will have an expiry date of no later than 180 days after the Maturity Date, but Borrower’s reimbursement obligation will be secured by cash in an amount equal to 105% of the face amount of all such Letters of Credit plus all interest, fees, and costs due or to become due in connection therewith on terms acceptable to Bank at any time after the Maturity Date if such Maturity Date is not extended by Bank or if an Event of Default occurs and continues. Borrower agrees to execute any further documentation in connection with the Letters of Credit as Bank may reasonably request.

               (b) Prior to or simultaneously with the opening of each Letter of Credit, Borrower shall pay to Bank Bank’s customary fees (subject to negotiation) in connection with the opening of a letter of credit (the “Letter of Credit Fees”). The Letter of Credit Fees shall be paid upon the opening of each Letter of Credit and upon each anniversary thereof, if required. In addition, Borrower shall pay to Bank, for its own account, any and all additional issuance, negotiation, processing, transfer or other fees to the extent and as and when required by the provisions of any application for Letters of Credit. All Letter of Credit Fees shall be part of the Obligations.

               (c) If any Letter of Credit is drawn upon, such amount shall constitute an Advance but shall be immediately due and payable. If such amount is not paid immediately, then the full amount thereof shall accrue interest at the rate set forth in Section 2.4(a).

     2.2 Equipment Advances.

               (a) Through December 16, 2005 (the “Equipment Availability End Date”), Bank will make advances (each, an “Equipment Advance” and, collectively, “Equipment Advances”) not exceeding the Committed Equipment Line. The Equipment Advances may only be used to purchase or refinance Equipment within 90 days of the invoice date, or, in the case of the initial advance, purchased on or after September 1, 2004.

               (b) Interest accrues from the date of each Equipment Advance (each, an “Equipment Advance Funding Date”) at the rate in Section 2.4(a). Each Equipment Advance is payable in 36 equal monthly installments of principal, plus accrued interest, beginning on the first of the month following the Equipment Advance Funding Date for such Equipment Advance and ending on the Equipment Maturity Date for such Equipment Advance. Equipment Advances when repaid may not be reborrowed.

               (c) To obtain an Equipment Advance, Borrower must provide notice in the form of a Payment/Advance Form to Bank (the notice is irrevocable) by facsimile no later than 12:00 noon Pacific Time one Business Day before the day on which the Equipment Advance is to be made. The Payment/Advance Form must be signed by a Responsible Officer or designee and include a copy of the invoice for the Equipment being financed.

               (d) The outstanding principal amount of term loans previously advanced by Bank to Borrower pursuant to that certain Loan and Security Agreement dated

March 28, 2003, as amended by that Amendment to Loan Documents dated July 17, 2003, as further amended by that certain Amendment to Loan Documents dated September 26, 2003, and Amended and Restated Loan and Security Agreement dated December 19, 2003 are set forth on Schedule A attached hereto (the “Existing Equipment Debt”). The Existing Equipment Debt shall, for all purposes hereof, be “Equipment Advances” hereunder and be governed by all the terms and conditions of this Agreement, except that the principal of said Existing Equipment Debt shall continue to be payable as set forth on Schedule A.

     2.3 Overadvances.

     If, at any time, Borrower’s Obligations hereunder exceed the Committed Revolving Line, Borrower shall immediately pay Bank the excess.

     2.4 Interest Rate, Payments.

               (a) Advances. Advances accrue interest on the outstanding principal balance thereof at a per annum rate equal to the Prime Rate. Equipment Advances, including the Existing Equipment Debt, accrue interest on the outstanding principal balance thereof at a per annum rate equal to one-half percentage point (0.50%) above the Prime Rate. After an Event of Default has occurred, Obligations shall accrue interest at a rate per annum equal to two percent (2%) above the rate effective immediately before the Event of Default. The interest rate increases or decreases when the Prime Rate changes. Interest is computed on a 360 day year for the actual number of days elapsed.

               (b) Payments. Interest due on the Advances and Equipment Advances is payable on the first of each month. Bank may debit any of Borrower’s deposit accounts, including account number 0341964970, for principal and interest payments owing or any amounts Borrower owes Bank. Bank will notify Borrower when it debits Borrower’s accounts. These debits are not a set-off. Payments received after 12:00 noon Pacific Time are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest accrue.

     2.5 Fees.

          Borrower will pay:

               (a) Loan Fee. Fully earned, non-refundable loan fees in the amount of $20,000 for the Committed Revolving Line and in the amount of $4,800 for the Committed Equipment Line are due on or before the Closing Date. If, at any time, Borrower fails to maintain a minimum aggregate amount of $20,000,000 of unrestricted funds on deposit for 10 consecutive Business Days with SVB Asset Management and/or SVB Securities, Borrower shall pay an additional $30,000 fee for the Committed Revolving Line and an additional $7,200 fee for the Committed Equipment Line.

               (b) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses) incurred through the date of this Agreement are payable upon demand, and Bank Expenses incurred after the date of this Agreement are payable within ten

(10) Business Days after delivery of invoice to Borrower.

     Bank’s obligation to make the initial Credit Extension is subject to the condition precedent that it receive the agreements, documents, and fees it requires.

     3.2 Conditions Precedent to all Credit Extensions.

               (b) the representations and warranties in Section 5 must be materially true on the date of the Payment/Advance Form and on the effective date of each Advance and no Event of Default may have occurred and be continuing, or result from such Advance. Each Credit Extension is Borrower’s representation and warranty on that date that the representations and warranties of Section 5 remain true in all material respects; provided, however, that those representations and warranties expressly referring to another date shall be true in all material respects as of such date only.

4. Creation Of Security Interest

     4.1 Grant of Security Interest.

     Borrower grants Bank a continuing security interest in all presently existing and later acquired Collateral to secure all Obligations and performance of each of Borrower’s duties under the Loan Documents. Any security interest will be a first priority security interest in the Collateral. If this Agreement is terminated, Bank’s lien and security interest in the Collateral will continue until Borrower fully satisfies its Obligations (other than inchoate indemnity obligations).

     4.2 Authorization to File; Delivery of Additional Documentation.

     Borrower authorizes Bank to file financing statements without notice to Borrower, with all appropriate jurisdictions, as Bank deems appropriate, in order to perfect or protect Bank’s security interest in the Collateral. Borrower shall execute and deliver to Bank, at the request of Bank, all documents that Bank may reasonably request, in form satisfactory to Bank, to perfect and continue perfected Bank’s security interest in the Collateral and in order to fully consummate all of the transactions contemplated under the Loan Documents.

5. Representations And Warranties

     Borrower represents and warrants as follows:

     5.1 Due Organization; Organizational Structure; Authorization.

     Borrower and each Subsidiary is duly existing and in good standing in its state of formation and qualified and licensed to do business in, and in good standing in, any state in which the conduct of its business or its ownership of property requires that it be qualified, except where the failure to do so could not reasonably be expected to cause a Material Adverse Change.

     Borrower has not changed its state of formation or organizational structure or type or any organizational number assigned by its jurisdiction of formation.

     The execution, delivery and performance of the Loan Documents have been duly authorized, and do not conflict with Borrower’s formation documents, nor constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which or by which it is bound in which the default could reasonably be expected to cause a Material Adverse Change.

     5.2 Places of Business; Location of Collateral.

     Except as set forth in the Disclosure Letter, the Equipment and Inventory is not in the possession of any third party bailee (such as at a warehouse, but excluding Equipment or Inventory in the possession of third parties for demonstration or evaluation purposes, or otherwise in the ordinary course of business consistent with past practices). In the event that Borrower, after the date hereof, intends to store or otherwise deliver the Collateral to such a bailee, then Borrower may amend the Disclosure Letter so long as such new location is within the continental United States.

     5.3 Collateral.

               (a) Borrower has rights in the Collateral and its Intellectual Property sufficient to grant a security interest therein, free of Liens except Permitted Liens.

The Accounts are bona fide, existing obligations, and the service or property has been performed or delivered to the account debtor or its agent for immediate shipment to and unconditional acceptance by the account debtor. All Inventory is in all material respects of good and marketable quality, free from material defects. Borrower is the sole owner of the Intellectual Property, except for non-exclusive and exclusive licenses granted in the ordinary course of business. Each issued Patent owned by Borrower is valid and enforceable and no part of the Intellectual Property has been judged invalid or unenforceable, in whole or in part, and no claim has been made that any part of the Intellectual Property violates the rights of any third party, except to the extent such claim could not reasonably be expected to cause a Material Adverse Change. None of the Equipment financed by Bank now is or will be affixed to any real property in such a manner, or with such intent, as to become a fixture.

               (b) All statements made and all unpaid balances appearing in all invoices, instruments, and other documents evidencing the Accounts are and shall be true and correct. All such invoices, instruments, and other documents, and all of Borrower’s Books are and shall be genuine and in all respects are what they purport to be. All sales and other transactions underlying or giving rise to each Account shall comply in all material respects with

all applicable laws and governmental rules and regulations. To the best of Borrower’s knowledge, all signatures and endorsements on all documents, instruments, and agreements relating to all Accounts are and shall be genuine, and all such documents, instruments, and agreements are and shall be legally enforceable in accordance with their terms.

     5.4 Litigation.

     Except as shown in the Disclosure Letter, there are no actions or proceedings pending or, to the knowledge of Borrower’s Responsible Officers, threatened by or against Borrower or any Subsidiary in which a likely adverse decision could reasonably be expected to cause a Material Adverse Change.

     5.5 No Material Adverse Change in Financial Statements.

     All consolidated financial statements for Borrower, and any Subsidiary, delivered to Bank fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s consolidated results of operations.

     5.6 Taxes.

     As of the date hereof, and except as set forth on the Disclosure Letter, Borrower is unaware of any claims or adjustments proposed for any of Borrower’s prior tax years which could result in additional taxes becoming due and payable by Borrower.

     5.7 Solvency.

     The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; the Borrower’s remaining assets after the transactions contemplated herein are not unreasonably small in relation to its business; and Borrower is able to pay its debts (including trade debts) as they mature.

     5.8 Existing Term Debt.

     Schedule A accurately reflects the outstanding principal amount, payment amounts, and maturity dates with respect to the Existing Equipment Debt.

     5.9 Regulatory Compliance.

     Borrower is not an “investment company” or a company “controlled” by an “investment company” under the Investment Company Act. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations T and U of the Federal Reserve Board of Governors). Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be expected to cause a Material Adverse Change. None of Borrower’s or any Subsidiary’s properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing, treating, or

transporting any hazardous substance other than legally. Borrower and each Subsidiary has timely filed all required tax returns and paid, or made adequate provision to pay, all material taxes, except those being contested in good faith with adequate reserves under GAAP. Borrower and each Subsidiary has obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all government authorities that are necessary to continue its business as currently conducted, except where the failure to do so could not reasonably be expected to cause a Material Adverse Change.

     5.10 Subsidiaries.

     Borrower does not own any stock, partnership interest or other equity securities except for Permitted Investments.

     5.11 Full Disclosure.

     No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank (taken together with all such written certificates and written statements to Bank) contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained in the certificates or statements not misleading (it being recognized by Bank that the projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are not viewed as facts and that actual results during the period or periods covered by such projections and forecasts may differ from the projected and forecasted results).

6. Affirmative Covenants

     6.1 Government Compliance.

     Subject to Section 7.3, Borrower will maintain its and all Subsidiaries’ legal existence and good standing in its jurisdiction of formation and maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to cause a material adverse effect on Borrower’s business or operations. Borrower will comply, and have each Subsidiary comply, with all laws, ordinances and regulations to which it is subject, noncompliance with which could have a material adverse effect on Borrower’s business or operations or would reasonably be expected to cause a Material Adverse Change.

     6.2 Financial Statements, Reports, Certificates.

accounting firm reasonably acceptable to Bank; (iii) annual financial projections in form and substance commensurate with those provided to Borrower’s board of directors or utilized by Borrower’s executive management, in form and substance satisfactory to Bank; (iv) within 5 days of filing, copies of all statements, reports and notices made available to Borrower’s security holders or to any holders of Subordinated Debt and all reports on Form 10-K, 10-Q and 8-K filed with the Securities and Exchange Commission (the “SEC”) (other than those reports on Form 10-K, 10-Q or 8-K (relating to certification) that are otherwise publicly available through the SEC’s EDGAR system); (v) a prompt report of any claim, proceeding, litigation, or investigation in the future threatened or instituted against Borrower which would reasonably be expected to result in damages to Borrower of $500,000 or more, exclusive of litigation the potential liability in connection with which is fully insured against; and (vi) budgets, sales projections, operating plans or other financial information Bank reasonably requests.

               (b) Within 45 days after the last day of each quarter, Borrower will deliver to Bank with the quarterly financial statements a Compliance Certificate.

               (c) Borrower will allow Bank to audit Borrower’s Collateral at Borrower’s expense, and the charge therefor shall be $750 per person per day (or such higher amount as shall represent Bank’s then current standard charge for the same), plus reasonable out-of-pocket expenses. In the event Borrower and Bank schedule and audit more than 10 days in advance, and Borrower seeks to reschedule the audit with less than 10 days written notice to Bank, then (without limiting any of Bank’s rights and remedies) Borrower shall pay Bank a cancellation fee of $1,000 plus any out-of-pocket expenses incurred by Bank to compensate Bank for the anticipated costs and expenses of cancellation. The results of audits will be satisfactory to Bank, and audits will be conducted no more often than once every year unless an Event of Default shall have occurred.

     6.3 Inventory; Returns.

     Borrower will keep all Inventory in good and marketable condition, free from material defects. Returns and allowances between Borrower and its account debtors will follow Borrower’s customary practices as they exist at execution of this Agreement. Borrower must promptly notify Bank of all returns, recoveries, disputes and claims that occur after the occurrence and during the continuance of an Event of Default.

     6.4 Collateral.

               (a) Borrower will give Bank at least 30 days prior written notice before opening any additional place of business, changing its chief executive office, or moving any of the Equipment or Inventory (but excluding Equipment or Inventory in the possession of third parties for documentation or evaluation purposes, or otherwise in the ordinary course of business consistent with past practices) to a location other than Borrower’s address set forth in the preamble hereof or in the Disclosure Letter, except that Borrower may maintain sales offices in the ordinary course of business at which not more than a total of $10,000 fair market value of Equipment is located.

               (b) In the event that Borrower shall at any time after the date hereof have any commercial tort claims against others, which it is asserting or intends to assert, and in which the likely recovery exceeds $1,000,000, Borrower shall promptly notify Bank thereof in writing and provide Bank with such information regarding the same as Bank shall request (unless providing such information would waive Borrower’s attorney-client privilege). Such notification to Bank shall constitute a grant of a security interest in the commercial tort claim and all proceeds thereof to Bank, and Borrower shall execute and deliver all such documents and take all such actions as Bank shall request in connection therewith.

     6.5 Taxes; Pension Contributions.

     Borrower will make, and cause each Subsidiary to make, timely payment of all material federal, state, and local taxes or assessments and will deliver to Bank, on demand, appropriate certificates attesting to the payment. Notwithstanding the foregoing, Borrower may defer payment of any contested taxes, provided that Borrower (a) in good faith contests its obligations to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (b) notifies Bank in writing of the commencement of, and any material development in, any such proceedings involving more than $500,000, and (c) posts bonds or takes other steps required to keep the contested taxes from becoming a lien upon any of the Collateral. Borrower has paid, and shall continue to pay all amounts necessary to fund all present and future pension, profit sharing, and deferred compensation plans in accordance with their terms, and Borrower has not and will not withdraw from participation in, permit partial or complete termination of, or permit the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of Borrower, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency.

     6.6 Insurance.

     Borrower will keep its business and the Collateral insured for risks and in amounts standard for Borrower’s industry, and as Bank may reasonably request. Insurance policies will be in a form, with companies, and in amounts that are satisfactory to Bank in Bank’s reasonable discretion. All property policies will have a lender’s loss payable endorsement showing Bank as an additional loss payee and all liability policies will show the Bank as an additional insured and provide that the insurer must give Bank at least 20 days notice before canceling its policy. At Bank’s request, Borrower will deliver certified copies of policies and evidence of all premium payments. Proceeds payable under any policy will, at Bank’s option if an Event of Default has occurred and is continuing, be payable to Bank on account of the Obligations. Bank shall release to Borrower, so long as no Event of Default is reasonably likely to occur as a result of such release by Bank, insurance proceeds with respect to Equipment which proceeds shall be utilized by Borrower for the replacement of the Equipment with respect to which the insurance proceeds were paid. Bank may require reasonable assurance that the insurance proceeds were utilized by Borrower for such purpose.

     9.1 Rights and Remedies.

     When an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the following:

               (a) Declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations are immediately due and payable without any action by Bank);

               (b) Stop advancing money or extending credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Bank;

               (c) Settle or adjust disputes and claims directly with account debtors for amounts, on terms and in any order that Bank considers advisable;

               (d) Make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral. Borrower will assemble the Collateral if Bank requires and make it available as Bank designates. Bank may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies;

               (e) Apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or the account of Borrower;

               (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Bank is granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s labels, Patents, Copyrights, Mask Works, rights of use of any name, trade secrets, trade names, Trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in completing

production of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit; and

               (g) Dispose of the Collateral according to the Code.

     9.2 Power of Attorney.

     Effective only when an Event of Default occurs and continues, Borrower irrevocably appoints Bank as its lawful attorney to: (a) endorse Borrower’s name on any checks or other forms of payment or security; (b) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against account debtors, (c) make, settle, and adjust all claims under Borrower’s insurance policies; (d) settle and adjust disputes and claims about the Accounts directly with account debtors, for amounts and on terms Bank determines reasonable; and (e) transfer the Collateral into the name of Bank or a third party as the Code permits. Bank may exercise the power of attorney to sign Borrower’s name on any documents necessary to perfect or continue the perfection of any security interest regardless of whether an Event of Default has occurred. Bank’s appointment as Borrower’s attorney in fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates.

     9.3 Accounts Collection.

     When an Event of Default occurs and continues, (a) Bank may notify any Person owing Borrower money of Bank’s security interest in the funds and verify the amount of the Account, and (b) Borrower must collect all payments in trust for Bank and, if requested by Bank, immediately deliver the payments to Bank in the form received from the account debtor, with proper endorsements for deposit.

     9.4 Bank Expenses.

     If Borrower fails to pay any amount or furnish any required proof of payment to third persons, Bank may make all or part of the payment or obtain insurance policies required in Section 6.6, and take any action under the policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then applicable rate and secured by the Collateral. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default.

     9.5 Bank’s Liability for Collateral.

     If Bank complies with reasonable banking practices and the Code, it is not liable for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other person. Borrower bears all risk of loss, damage or destruction of the Collateral.

     9.6 Remedies Cumulative.

     Bank’s rights and remedies under this Agreement, the Loan Documents, and all other

agreements are cumulative. Bank has all rights and remedies provided under the Code, by law, or in equity. Bank’s exercise of one right or remedy is not an election, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay is not a waiver, election, or acquiescence. No waiver is effective unless signed by Bank and then is only effective for the specific instance and purpose for which it was given.

     9.7 Demand Waiver.

     Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Bank on which Borrower is liable.
