Amended and Restated Agreement between Silicon Valley Bank and the Registrant

 Exhibit 10.21 
  
 AMENDED AND RESTATED 
 LOAN AND SECURITY AGREEMENT 
  
 THIS AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT (together with any schedule, annex, or exhibit attached hereto, as the same may be amended, restated, or otherwise modified, this “Agreement”) is entered into on
June 15, 2004 (the “Effective Date”) between SILICON VALLEY BANK (“Bank”), whose address is 3003 Tasman Drive, Santa Clara, California 95054, and REDBACK NETWORKS INC., a Delaware corporation
(“Borrower”), whose chief executive office is 300 Holger Way, San Jose, California 95134 (“Borrower’s Address”), and amends, restates, replaces and supersedes in its entirety that certain Loan and Security
Agreement dated the Original Closing Date, between Bank and Borrower. (Definitions of capitalized terms used in this Agreement are set forth in Section 8 below.) 
  
 1. ADVANCES. 
  
 1.1 Advances. Bank will make advances (collectively, the “Advances”) to Borrower up to the amounts shown on the Schedule,
provided no Default or Event of Default has occurred and is continuing, and subject to deduction of Reserves. 
  
 1.2 Interest. All Advances, Bank Expenses, and other fees shall bear interest at the rate shown on the Schedule, except where expressly set
forth to the contrary in this Agreement. Interest shall be payable monthly, in arrears, on the last day of the month. Interest shall be charged to a deposit account with Bank designated by Borrower, or if no funds are available in any such deposit
account, as an Advance under this Agreement. 
  
 1.3
Overadvances. Subject to the terms set forth in the Schedule, if at any time or for any reason the total of all outstanding Advances and all other monetary Obligations exceeds (a) the sum of the Credit Limit and the Permitted Overadvances,
or (b) if the Increased Overadvance Option is in effect, the sum of the Credit Limit and the Increased Permitted Overadvances (each of the conditions in (a) or (b), an “Overadvance”), Borrower shall immediately pay the amount of the
excess to Bank, without notice or demand. Without limiting Borrower’s obligation to repay to Bank the amount of any Overadvance, Borrower agrees to pay Bank interest on the outstanding amount of any Overadvance that is not a Permitted
Overadvance or an Increased Permitted Overadvance, on demand, at the Default Rate. 
  
 1.4 Fees. Borrower shall pay Bank the fees shown on the Schedule, which are in addition to all interest and other sums payable to Bank and are not refundable. 
  
 1.5 Advance Requests. To obtain an Advance, Borrower shall make
a request to Bank by facsimile or telephone. Advance requests received after 12:00 Noon Pacific time will not be considered by Bank until the next Business Day. Bank may rely on any telephone request for a Advance given by a person whom Bank
reasonably believes is an authorized representative of Borrower, and Borrower will indemnify Bank for any loss Bank suffers as a result of that reliance. 

 1.6 Letters of Credit. At the request of Borrower, Bank may, in its good faith business
judgment, issue or arrange for the issuance of letters of credit for the account of Borrower, in each case in form and substance satisfactory to Bank in its sole discretion (collectively, “Letters of Credit”). The aggregate face
amount of all Letters of Credit from time to time outstanding shall not exceed the Letter of Credit Sublimit shown on the Schedule, and shall be reserved against the Borrowing Base which would reduce the availability of Advances hereunder, and in
the event at any time there is insufficient availability under the Borrowing Base for such reserve, Borrower shall deposit and maintain with Bank cash collateral, or maintain securities acceptable to Bank and subject to a securities account control
agreement, in an amount at all times equal to such deficiency, which shall be held as Collateral for all purposes of this Agreement. Upon Borrower’s request, Bank will release any such deposit to Borrower to the extent there is additional
availability under the Borrowing Base. Borrower shall pay all bank charges (including charges of Bank) for the issuance of Letters of Credit, together with such additional fee as Bank’s letter of credit department shall charge in connection
with the issuance of the Letters of Credit or as set forth in the Standby Letter of Credit Application completed by Borrower. Any payment by Bank under or in connection with a Letter of Credit shall constitute an Advance hereunder on the date such
payment is made. Each Letter of Credit shall have an expiry date no later than thirty days prior to the Maturity Date. Borrower hereby agrees to indemnify and hold Bank harmless from any loss, cost, expense, or liability, including payments made by
Bank, expenses, and reasonable attorneys’ fees incurred by Bank arising out of or in connection with any Letters of Credit; except to the extent any such loss, cost, expense or liability arises from the gross negligence or willful misconduct of
Bank. Borrower agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guarantied by Bank and opened for Borrower’s account or by Bank’s interpretations of any Letter of Credit issued by Bank for
Borrower’s account, and Borrower understands and agrees that Bank shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrower’s instructions or those contained in the Letters of
Credit or any modifications, amendments, or supplements thereto, except in the case of gross negligence or willful misconduct. Borrower understands that Letters of Credit may require Bank to indemnify the issuing bank for certain costs or
liabilities arising out of claims by Borrower against such issuing bank. Borrower hereby agrees to indemnify and hold Bank harmless with respect to any loss, cost, expense, or liability incurred by Bank under any Letter of Credit as a result of
Bank’s indemnification of any such issuing bank. The provisions of this Agreement, as it pertains to Letters of Credit, and any other Loan Document relating to Letters of Credit are cumulative. To the extent the terms of any letter of credit
application are in conflict with this Agreement, the terms of this Agreement shall control. The Jabil LC is hereby deemed to have been issued hereunder and is expressly made subject to the terms and conditions of this Agreement. 
  
 2. SECURITY INTEREST. To secure the payment and performance of
all of the Obligations when due, Borrower hereby grants to Bank a security interest in all of the following (collectively, the “Collateral”): all right, title and interest of Borrower in and to all of the following, whether now
owned or hereafter arising or acquired and wherever located: all Accounts; all Inventory; all Equipment; all Deposit Accounts; all General Intangibles (including without limitation all Intellectual Property); all Investment Property (excluding 35%
of the equity interests of Subsidiaries formed in jurisdictions outside of the United States); all Other Property; and any and all claims, rights and interests in any of the above, and all guaranties and security for any of the above, and all
substitutions and replacements for, additions, accessions, attachments, accessories, and improvements to, and proceeds (including proceeds of any insurance policies, proceeds of proceeds and claims against third parties) of, any and all of the
above, and all Borrower’s books relating to any and all of the above.

 3. REPRESENTATIONS, WARRANTIES AND COVENANTS OF BORROWER. 
  
 In order to induce Bank to enter into this Agreement and to make Advances,
and except to the extent set forth in the Representations, Borrower represents and warrants to Bank as follows, and Borrower covenants that the following representations will continue to be true at all times, and that Borrower will at all times
comply with all of the following covenants, throughout the term of this Agreement and until all Obligations have been paid and performed in full: 
  
 3.1 Corporate Existence and Authority. Borrower is and will continue to be, duly organized, validly existing and in good standing under the
laws of the State of Delaware. Borrower is and will continue to be qualified and licensed to do business in Delaware, California, and all jurisdictions in which any failure to do so would result in a Material Adverse Change. The execution, delivery
and performance by Borrower of this Agreement, and all other documents contemplated hereby (a) have been duly and validly authorized, (b) are enforceable against Borrower in accordance with their terms (except as enforcement may be limited by
equitable principles and by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to creditors’ rights generally), (c) do not violate Borrower’s Certificate of Incorporation, or Borrower’s by-laws, or any law or
any material agreement or instrument which is binding upon Borrower or its property, and (d) do not constitute grounds for acceleration of any material indebtedness or obligation under any agreement or instrument which is binding upon Borrower or
its property. 
  
 3.2 Name; Trade Names and Styles.
The name of Borrower set forth in the heading to this Agreement, or such other name of which it has notified Bank in accordance with this Section 3.2, is its correct name. Listed in the Representations are all prior names of Borrower and all of
Borrower’s present and prior trade names. Borrower shall give Bank 30 days prior written notice before changing its name or doing business under any other name. Borrower has complied, and will in the future comply, in all material respects,
with all laws relating to the conduct of business under a fictitious business name, except where the failure to so comply would not reasonably be expected to result in a Material Adverse Change. 
  
 3.3 Place of Business; Location of Collateral. The address set
forth in the heading to this Agreement as Borrower’s address (or such other address of which Borrower has given Bank notice pursuant to this Section 3.3) is Borrower’s chief executive office. In addition, Borrower has places of business
and Collateral is located only at the locations set forth in the Representations (or such other locations of which Borrower has given or will give Bank notice pursuant to this Section 3.3). Borrower will give Bank at least ten days prior written
notice before opening any additional place of business, changing its chief executive office, or moving any of the Collateral to a location other than Borrower’s Address or one of the locations set forth in the Representations, except that
Borrower may maintain sales offices in the ordinary course of business at which not more than a total of $50,000 fair market value of Equipment is located. 
  

 -3- 

 3.4 Title to Collateral; Perfection; Permitted Liens. 
  
 (a) Borrower is now, and will at all times in the future be, the sole owner
of all the Collateral, except for items of Equipment which are leased or licensed to Borrower. The Collateral now is and will remain free and clear of any and all liens, charges, security interests, encumbrances and adverse claims, except for
Permitted Liens. Bank now has, and will continue to have, a first-priority perfected and enforceable security interest in all of the Collateral, subject only to the Permitted Liens, and Borrower will at all times defend Bank and the Collateral
against all claims of others. 
  
 (b) Borrower has set forth in
the Representations all of Borrower’s Deposit Accounts. Borrower will give Bank five Business Days advance written notice before establishing any Deposit Account with a bank other than Bank and will cause the institution where any such new
Deposit Account is maintained to execute and deliver to Bank a control agreement in form sufficient to perfect Bank’s security interest in the Deposit Account and otherwise satisfactory to Bank in its good faith business judgment. Nothing
herein limits any requirements which may be set forth in the Schedule as to where Deposit Accounts will be maintained. 
  
 (c) In the event that Borrower shall at any time after the date hereof have any commercial tort claims against others, which it is asserting, and in which
the potential recovery exceeds $100,000, 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 the 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. 
  
 (d) None of the
Collateral now is or will be affixed to any real property in such a manner, or with such intent, as to become a fixture. Borrower is not and will not become a lessee under any real property lease pursuant to which the lessor may obtain any rights in
any of the Collateral and no such lease now prohibits, restrains, impairs or will prohibit, restrain or impair Borrower’s right to remove any Collateral from the leased premises. Whenever any Collateral is located upon premises in which any
third party has an interest, Borrower shall, whenever requested by Bank, use commercially reasonable efforts to cause such third party to execute and deliver to Bank, in form acceptable to Bank, such waivers and subordinations as Bank shall specify
in its good faith business judgment. In the event that such waivers and subordinations are not obtained, Bank may, in its discretion, establish appropriate reserves against the Borrowing Base. Borrower will keep in full force and effect, and will
comply with all material terms of, any lease of real property where any of the Collateral now or in the future may be located. 
  
 3.5 Maintenance of Collateral. Borrower will maintain the Collateral in good working condition (ordinary wear and tear excepted), and
Borrower will not use the Collateral for any unlawful purpose. Borrower will promptly advise Bank in writing of any material loss or damage to the Collateral. 
  

 -4- 

 3.6 Books and Records. Borrower has maintained and will maintain at Borrower’s Address
books and records sufficient to prepare financial statements in accordance with GAAP. 
  
 3.7 Financial Condition, Statements and Reports. Subject to the absence of footnotes and year-end adjustments in the case of interim financial statements, all financial statements of Borrower and it
consolidated subsidiaries now or in the future delivered to Bank have been, and will be, prepared in conformity with GAAP and now and in the future will fairly present in all material respects the results of operations and financial condition of
Borrower and its consolidated subsidiaries, in accordance with GAAP, at the times and for the periods therein stated. Between the last date covered by any such statement provided to Bank and the date hereof, there has been no Material Adverse
Change. 
  
 3.8 Tax Returns and Payments; Pension
Contributions. Borrower has timely filed, and will timely file, all required tax returns and reports, and Borrower has timely paid, and will timely pay, all foreign, federal, state and local taxes, assessments, deposits and contributions now
or in the future owed by Borrower (it being understood that payment of certain taxes has been deferred and such taxes will be paid over time pursuant to Borrower’s Plan of Reorganization). Notwithstanding the foregoing, Borrower may, however,
defer payment of any contested taxes, provided that Borrower (a) in good faith contests Borrower’s obligation 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, the proceedings, and (c) posts bonds or takes any other steps required to keep the contested taxes from becoming a lien upon any of the Collateral. 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 that would result in a Material Adverse Change. 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 that
would result in a Material Adverse Change. 
  
 3.9
Compliance with Law. Borrower has, to its knowledge, complied, and will comply, in all material respects, with all provisions of all foreign, federal, state and local laws and regulations applicable to Borrower, including, but not limited
to, those relating to Borrower’s ownership of real or personal property, the conduct and licensing of Borrower’s business, and all environmental matters. 
  
 3.10 Litigation. There is no claim, suit, litigation, proceeding or investigation pending or (to
Borrower’s knowledge) threatened against Borrower in any court or before any governmental agency which could reasonably be expected to result, either separately or in the aggregate, in any Material Adverse Change. Borrower will promptly inform
Bank in writing of any claim, proceeding, litigation or investigation in the future threatened in writing or instituted against Borrower involving any single claim that can reasonably be expected to result in liability in excess of $100,000, or
$250,000 in the aggregate. 
  

 -5- 

 3.11 Use of Proceeds. All proceeds of all Advances shall be used solely for lawful business
purposes. Borrower is not purchasing or carrying any “margin stock” (as defined in Regulation U of the Board of Governors of the Federal Reserve System) and no part of the proceeds of any Advance will be used to purchase or carry any
“margin stock” or to extend credit to others for the purpose of purchasing or carrying any “margin stock,” in either case in violation of Regulation U. 
  
 4. ACCOUNTS. 
  
 4.1 Representations Relating to Accounts. Borrower represents and warrants to Bank as follows: Each Account with respect to which Advances
are requested by Borrower shall, on the date each Advance is requested and made (a) represent an undisputed bona fide existing unconditional obligation of the Account Debtor created by the sale, delivery, and acceptance of goods or the rendition of
services, or the non-exclusive licensing of Intellectual Property, in the ordinary course of Borrower’s business, and (b) meet the Minimum Domestic Eligibility Requirements or Minimum Foreign Eligibility Requirements, as the case may be, set
forth in Section 8 below. 
  
 4.2 Representations Relating
to Documents and Legal Compliance. Borrower represents and warrants to Bank as follows: 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 and all such invoices, instruments and other documents and all of Borrower’s books and records are and shall be genuine and in all respects 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 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 except to the extent that the enforceability thereof may be limited by applicable bankruptcy, insolvency,
moratorium and other similar laws affecting creditors’ rights generally and by equitable principles (regardless of whether enforcement is sought in equity or at law). 
  
 4.3 Schedules and Documents relating to Accounts. Borrower shall deliver to Bank transaction reports and
schedules of collections, as provided in the Schedule, on Bank’s standard forms; provided, however, that Borrower’s failure to execute and deliver the same shall not affect or limit Bank’s security interest and other rights in all of
Borrower’s Accounts, nor shall Bank’s failure to advance or lend against a specific Account affect or limit Bank’s security interest and other rights therein. If requested by Bank, Borrower shall furnish Bank with copies (or, at
Bank’s request, originals) of all contracts, orders, invoices, and other similar documents, and all shipping instructions, delivery receipts, bills of lading, and other evidence of delivery, for any goods the sale or disposition of which gave
rise to such Accounts, and Borrower warrants the genuineness of all of the foregoing. Borrower shall also furnish to Bank an aged accounts receivable trial balance as provided in the Schedule. In addition, Borrower shall deliver to Bank, on its
request, the originals of all instruments, chattel paper, security agreements, guarantees and other documents and property evidencing or securing any Accounts, in the same form as received, with all necessary endorsements, and copies of all credit
memos. 
  

 -6- 

 4.4 Collection of Accounts. Borrower shall have the right to collect all Accounts, unless
and until a Default or an Event of Default has occurred and is continuing. Whether or not an Event of Default has occurred and is continuing, Borrower shall hold all payments on, and proceeds of, Accounts in trust for Bank, and Borrower shall
immediately deliver all such payments and proceeds to Bank in their original form, duly endorsed, to be applied to the Obligations in such order as Bank shall determine (it being understood that no proceeds will be applied to undrawn amounts of
Letters of Credit). Borrower shall deposit all proceeds of Collateral into a lockbox account, or such other “blocked account” as Bank may specify, pursuant to a blocked account agreement in such form as Bank may specify in its good faith
business judgment. 
  
 4.5 Remittance of Proceeds.
All proceeds arising from the disposition of any Collateral shall be delivered, in kind, by Borrower to Bank in the original form in which received by Borrower not later than the following Business Day after receipt by Borrower, to be applied to the
Obligations in such order as Bank shall determine; provided that, if no Default or Event of Default has occurred and is continuing, Borrower shall not be obligated to remit to Bank the proceeds of the sale of worn out or obsolete Equipment disposed
of by Borrower in good faith in an arm’s length transaction for an aggregate purchase price of $500,000 or less (for all such transactions in any fiscal year). Borrower agrees that it will not commingle proceeds of Collateral with any of
Borrower’s other funds or property, but will hold such proceeds separate and apart from such other funds and property and in an express trust for Bank. Nothing in this Section limits the restrictions on disposition of Collateral set forth
elsewhere in this Agreement. 
  
 4.6 Disputes.
Borrower shall notify Bank promptly of all disputes or claims relating to Accounts. Borrower shall not forgive (completely or partially), compromise or settle any Account for less than payment in full, or agree to do any of the foregoing, except
that Borrower may do so, provided that: (a) Borrower does so in good faith, in a commercially reasonable manner, in the ordinary course of business, and in arm’s length transactions, which are reported to Bank on the regular reports provided to
Bank; (b) no Default or Event of Default has occurred and is continuing; and (c) taking into account all such discounts, settlements and forgiveness, the total outstanding Advances will not exceed the Credit Limit (unless arrangements are made to
reduce the amount of the outstanding Advances so that they will not exceed the Credit Limit). 
  
 4.7 Returns. Provided no Event of Default has occurred and is continuing, if any Account Debtor returns any Inventory to Borrower, Borrower shall promptly determine the reason for such return and, unless
such return is disputed by Borrower or unless such return is immediately replaced by Borrower, promptly issue a credit memorandum to the Account Debtor in the appropriate amount. In the event any attempted return occurs after the occurrence and
during the continuance of any Event of Default, Borrower shall hold the returned Inventory in trust for Bank, and immediately notify Bank of the return of the Inventory. 
  
 4.8 Verification. Bank may, from time to time, verify directly with the respective Account Debtors the
validity, amount and other matters relating to the Accounts, by means of mail, telephone or otherwise, either in the name of Borrower or Bank or such other name as Bank may choose. 
  

 -7- 

 4.9 No Liability. Bank shall not be responsible or liable for any shortage or discrepancy
in, damage to, or loss or destruction of, any goods, the sale or other disposition of which gives rise to an Account, or for any error, act, omission, or delay of any kind occurring in the settlement, failure to settle, collection or failure to
collect any Account, or for settling any Account in good faith for less than the full amount thereof, nor shall Bank be deemed to be responsible for any of Borrower’s obligations under any contract or agreement giving rise to an Account.
Nothing herein shall, however, relieve Bank from liability for its own gross negligence or willful misconduct. 
  
 5. ADDITIONAL DUTIES OF BORROWER. 
  
 5.1 Financial and Other Covenants. Borrower shall at all times comply with the financial and other covenants set forth in the Schedule. 
  
 5.2 Insurance. Borrower shall, at all times insure all of the tangible personal property Collateral and carry
such other business insurance, with insurers reasonably acceptable to Bank, in such form and amounts as Bank may reasonably require and that are customary and in accordance with standard practices for Borrower’s industry and locations, and
Borrower shall provide evidence of such insurance to Bank. All casualty insurance policies shall name Bank as loss payee and shall contain a lenders loss payee endorsement in form reasonably acceptable to Bank. All policies of liability insurance
shall name Bank as an additional insured. Upon receipt of the proceeds of any such insurance, Bank shall apply such proceeds in reduction of the Obligations as Bank shall determine in its good faith business judgment, except that, provided no
Default or Event of Default has occurred and is continuing, Bank shall release to Borrower casualty insurance proceeds totaling less than $250,000, which shall be utilized by Borrower for the replacement of the property with respect to which the
insurance proceeds were paid. Bank may require reasonable assurance that the insurance proceeds so released will be so used. If Borrower fails to provide or pay for any insurance, Bank may, but is not obligated to, obtain the same at Borrower’s
expense. Borrower shall promptly deliver to Bank copies of all material reports made to insurance companies. 
  
 5.3 Reports. Borrower, at its expense, shall provide Bank with the written reports set forth in the Schedule, and such other written reports
with respect to Borrower (including budgets, sales projections, operating plans and other financial documentation), as Bank shall from time to time reasonably specify in its good faith business judgment. 
  
 5.4 Access to Collateral, Books and Records. At reasonable
times, and on one Business Day’s notice, Bank, or its agents, shall have the right to inspect the Collateral and the right to audit and copy Borrower’s books and records. After the initial inspection and audit, such inspections and audits
shall occur quarterly or more frequently at Bank’s discretion. Bank shall take reasonable steps to keep confidential all information obtained in any such inspection or audit, but Bank shall have the right to disclose any such information to its
auditors, regulatory agencies, and attorneys, and pursuant to any subpoena or other legal process. The foregoing inspections and audits shall be 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; provided that so long as no Event of Default has occurred and is continuing, Borrower shall not be required to pay such
expenses more than once per fiscal quarter. In the event Borrower and Bank schedule an audit more than ten days in 
  

 -8- 

 advance, and Borrower seeks to reschedule the audit with less than ten days written notice to Bank, then (without
limiting any of Bank’s rights or 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 the cancellation. 
  
 5.5 Negative Covenants. Except as may be permitted in the
Schedule, Borrower shall not, and shall not permit any Subsidiary to, without Bank’s prior written consent (which shall be a matter of its good faith business judgment), do any of the following: 
  
 (a) merge or consolidate with another corporation or entity (except that a
Subsidiary may merge or consolidate with or into another Subsidiary or Borrower); or acquire all or substantially all of the capital stock or property of a Person other than a Subsidiary; provided that Borrower or a Subsidiary may merge or
consolidate with another corporation or entity or acquire all or substantially all of the capital stock or property of a Person other than a Subsidiary, if (i) a Default or Event of Default shall not have occurred and be continuing and would not
occur as a result of such transaction; and (ii) such transaction shall not result in a decrease in excess of 25% of Tangible Net Worth of Borrower on a consolidated basis after giving effect to the transaction; 
  
 (b) enter into any material transaction with any Affiliate of Borrower except
for (i) transactions that are in the ordinary course of Borrower’s business, upon fair and reasonable terms (when viewed in the context of any series of transactions of which it may be a part, if applicable); and (ii) transactions permitted
under Sections 5.5(f) or (i); 
  
 (c) Convey, sell, lease,
transfer or otherwise dispose of (collectively “Transfer”) all or any part of its business or property, except for: 
  
 (i) sales of Inventory in the ordinary course of business; 
  
 (ii) Transfers associated with the making or disposition of a Permitted Investment; 
  
 (iii) Dispositions of cash or Permitted Investments in a manner not prohibited by this Agreement; 
  
 (iv) Dispositions of obsolete, damaged or worn-out equipment in the ordinary
course of business; 
  
 (v) Licensing of intellectual property in
the ordinary course of business; and 
  
 (vi) Transfers not
otherwise permitted in this Section 5.5(c), provided, that the aggregate book value of all such other Transfers by Borrower and its Subsidiaries, together, shall not exceed in any fiscal year, $1,000,000; 
  
 (d) without prior written notice to Bank, store any Inventory or other
Collateral with any warehouseman or other third party not specified in the Representations or otherwise consented to in writing by Bank; 
  

 -9- 

 (e) sell any Inventory on a sale-or-return, guaranteed sale, consignment, or other contingent basis;

  
 (f) make any loans of any money or other assets except for
Permitted Investments; 
  
 (g) incur any Indebtedness, other than
Permitted Indebtedness; 
  
 (h) guarantee or otherwise become
liable with respect to the obligations of another party or entity other than Permitted Indebtedness; 
  
 (i) pay or declare any dividends on stock or redeem, retire, purchase or otherwise acquire, directly or indirectly, any of Borrower’s stock except
for Permitted Distributions; 
  
 (j) permit, vote in favor of, or
enter into any agreement that would result in, a Change of Control; 
  
 (k) engage, directly or indirectly, in any material line of business other than those lines of business conducted by Borrower and its Subsidiaries on the date hereof and any businesses reasonably related, complementary or incidental thereto
or reasonable extensions thereof; or 
  
 (l) with respect to
Borrower only, dissolve or elect to dissolve, or, without prior written notice to Bank, change its state of incorporation. 
  
 Transactions not otherwise prohibited by this Section 5.5 are only permitted if no Default or Event of Default would occur as a result of such
transaction. 
  
 5.6 Litigation Cooperation. Should
any third-party suit or proceeding be instituted by or against Bank with respect to any Collateral or relating to Borrower, Borrower shall, without expense to Bank, use reasonable efforts to make available Borrower and its officers, employees and
agents and Borrower’s books and records, to the extent that Bank may deem them reasonably necessary in order to prosecute or defend any such suit or proceeding. 
  
 5.7 Further Assurances. Borrower agrees, at its expense, on request by Bank, to execute all documents and take
all actions, as Bank, may, in its good faith business judgment, deem necessary or useful in order to perfect and maintain Bank’s perfected first-priority security interest in the Collateral (subject to Permitted Liens), and in order to fully
consummate the transactions contemplated by this Agreement. 
  
 6. TERM.

  
 6.1 Maturity Date. This Agreement shall
continue in effect until the maturity date set forth on the Schedule (the “Maturity Date”), subject to Section 6.3 below. 
  
 6.2 Early Termination. This Agreement may be terminated prior to the Maturity Date as follows: (a) by Borrower, effective three Business
Days after written notice of 
  

 -10- 

 termination is given to Bank; or (b) by Bank at any time after the occurrence and during the continuance of an Event of
Default, without notice, effective immediately. If this Agreement is terminated by Borrower or by Bank under this Section 6.2 prior to June 30, 2005, Borrower shall pay to Bank a termination fee in an amount equal to one percent (1.0%) of the
Maximum Credit Limit, provided that no termination fee shall be charged if (x) the credit facility hereunder is replaced with a new facility from another division of Silicon Valley Bank or (y) Borrower is subject to and in compliance with the First
Reset Conditions. The termination fee shall be due and payable on the effective date of termination and thereafter shall bear interest at a rate equal to the highest rate applicable to any of the Obligations. 
  
 6.3 Payment of Obligations. On the Maturity Date or on any
earlier effective date of termination, Borrower shall pay and perform in full all Obligations, whether evidenced by installment notes or otherwise, and whether or not all or any part of such Obligations are otherwise then due and payable. Without
limiting the generality of the foregoing, if on the Maturity Date, or on any earlier effective date of termination, there are any outstanding Letters of Credit issued by Bank or issued by another institution based upon an application, guarantee,
indemnity or similar agreement on the part of Bank, then on such date Borrower shall provide to Bank cash collateral 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 (as estimated by Bank in its good faith business judgment), to secure all of the Obligations relating to said Letters of Credit, pursuant to Bank’s then standard form cash pledge agreement. Notwithstanding any
termination of this Agreement, all of Bank’s security interests in all of the Collateral and all of the terms and provisions of this Agreement shall continue in full force and effect until all Obligations have been paid and performed in full;

reasonable manner: (a) Execute on behalf of Borrower any documents that Bank may, in its good faith business judgment, deem advisable in order to perfect and maintain Bank’s security interest in the Collateral, or in order to exercise a right
of Borrower or Bank, or in order to fully consummate all the transactions contemplated under this Agreement, and all other Loan Documents; (b) Execute on behalf of Borrower, any invoices relating to any Account, any draft against any Account Debtor

foregoing shall be added to and become part of the Obligations, shall be payable on demand, and shall bear interest at a rate equal to the highest interest rate applicable to any of the Obligations. In no event shall Bank’s rights under the
foregoing power of attorney or any of Bank’s other rights under this Agreement be deemed to indicate that Bank is in control of the business, management or properties of Borrower. 
  

 -14- 

 7.5 Application of Proceeds. All proceeds realized as the result of any sale of the
Collateral shall be applied by Bank, first, to the costs, expenses, liabilities, obligations and attorneys’ fees incurred by Bank in the exercise of its rights under this Agreement, second, to the interest due upon any of the Obligations, and
third, to the principal of the Obligations, in such order as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower or other persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If,
Bank, in its good faith business judgment, directly or indirectly enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Bank shall have the option, exercisable at any time, in its good faith
business judgment, of either reducing the Obligations by the principal amount of purchase price or deferring the reduction of the Obligations until the actual receipt by Bank of the cash therefor. 
  
 7.6 Remedies Cumulative. In addition to the rights and remedies
set forth in this Agreement, Bank shall have all the other rights and remedies accorded a secured party under the Code and under all other applicable laws, and under any other instrument or agreement now or in the future entered into between Bank
and Borrower, and all of such rights and remedies are cumulative and none is exclusive. Exercise or partial exercise by Bank of one or more of its rights or remedies shall not be deemed an election, nor bar Bank from subsequent exercise or partial

been fully paid and performed.

 9.1 Interest Computation; Float Charge. In computing interest
on the Obligations, all Payments received after 12:00 noon Pacific time on any day shall be deemed received on the next Business Day. In addition, whenever Advances are outstanding, Bank shall be entitled to charge Borrower a “float”
charge in an amount equal to three Business Days interest, at the interest rate applicable to the Loans, on all Payments received by Bank. The float charge for each month shall be payable on the last day of the month. Bank shall not, however, be
required to credit Borrower’s account for the amount of any item of payment which is unsatisfactory to Bank in its good faith business judgment, and Bank may charge Borrower’s loan account for the amount of any item of payment which is
returned to Bank unpaid. 
  
 9.2 Application of
Payments. All payments with respect to the Obligations may be applied, and in Bank’s good faith business judgment reversed and re-applied, to the Obligations, in such order and manner as Bank shall determine in its good faith business
judgment. 
  

 -26- 

 9.3 Charges to Accounts. Bank may, in its discretion, require that Borrower pay monetary
Obligations in cash to Bank or charge any monetary Obligations to Borrower’s deposit accounts maintained with Bank, or, if no amounts are available in such deposit accounts, charge them to Borrower’s loan account with Bank, in which event
they will bear interest at the same rate applicable to the Advances. 
  
 9.4 Monthly Accountings. Bank shall provide Borrower monthly with an account of advances, charges, expenses and payments made pursuant to this Agreement. Such account shall be deemed correct, accurate and binding on Borrower
and an account stated (except for reverses and reapplications of payments made and corrections of errors discovered by Bank), unless Borrower notifies Bank in writing to the contrary within 60 days after such account is rendered, describing the
nature of any alleged errors or omissions. 
  
 9.5
Notices. All notices to be given under this Agreement shall be in writing and shall be given either personally or by reputable private delivery service or by regular first-class mail, or certified mail return receipt requested, addressed to
Bank or Borrower at the addresses shown in the heading to this Agreement, or at any other address designated in writing by one party to the other party. Notices to Bank shall be directed to the Commercial Finance Division, to the attention of the

 9.6 Severability. Should any provision of this Agreement be held by any court of competent jurisdiction to be void or unenforceable, such
defect shall not affect the remainder of this Agreement, which shall continue in full force and effect. 
  
 9.7 Integration. This Agreement and such other written agreements, documents and instruments as may be executed in connection herewith are
the final, entire and complete agreement between Borrower and Bank and supersede all prior and contemporaneous negotiations and oral representations and agreements, all of which are merged and integrated in this Agreement. There are no oral
understandings, representations or agreements between the parties which are not set forth in this Agreement or in other written agreements signed by the parties in connection herewith. 
  
 9.8 Waivers; Indemnity. The failure of Bank at any time or
times to require Borrower to strictly comply with any of the provisions of this Agreement or any other Loan Document shall not waive or diminish any right of Bank later to demand and receive strict compliance therewith. Any waiver of any default
shall not waive or affect any other default, whether prior or subsequent, and whether or not similar. None of the provisions of this Agreement or any other Loan Document shall be deemed to have been waived by any act or knowledge of Bank or its
agents or employees, but only by a specific written waiver signed by an authorized officer of Bank and delivered to Borrower. Borrower waives the benefit of all statutes of limitations relating to any of the Obligations or this Agreement or any
other Loan Document, and Borrower waives demand, protest, notice of protest and notice of default or dishonor, notice of payment and nonpayment, release, compromise, settlement, extension or renewal of any commercial paper, instrument, account,
General Intangible, document or 
  

 -27- 

 guaranty at any time held by Bank on which Borrower is or may in any way be liable, and notice of any action taken by
Bank, unless expressly required by this Agreement. Borrower hereby agrees to indemnify Bank and its affiliates, subsidiaries, parent, directors, officers, employees, agents, and attorneys, and to hold them harmless from and against any and all
claims, debts, liabilities, demands, obligations, actions, causes of action, penalties, costs and expenses (including reasonable attorneys’ fees), of every kind, which they may sustain or incur based upon or arising out of any of the
Obligations, or any relationship or agreement between Bank and Borrower, or any other matter, relating to Borrower or the Obligations; provided that this indemnity shall not extend to damages proximately caused by the indemnitee’s own gross
negligence or willful misconduct. Notwithstanding any provision in this Agreement to the contrary, the indemnity agreement set forth in this Section shall survive any termination of this Agreement and shall for all purposes continue in full force
and effect. 
  
 9.9 No Liability for Ordinary
Negligence. Neither Bank, nor any of its directors, officers, employees, agents, attorneys or any other Person affiliated with or representing Bank shall be liable for any claims, demands, losses or damages, of any kind whatsoever, made,
claimed, incurred or suffered by Borrower or any other party through the ordinary negligence of Bank, or any of its directors, officers, employees, agents, attorneys or any other Person affiliated with or representing Bank, but nothing herein shall
relieve Bank from liability for its own gross negligence or willful misconduct. 
  
 9.10 Amendment. The terms and provisions of this Agreement may not be waived or amended, except in a writing executed by Borrower and a duly authorized officer of Bank. 
  
 9.11 Time of Essence. Time is of the essence in the performance
by Borrower of each and every obligation under this Agreement. 
  
 9.12 Attorneys’ Fees and Costs. Borrower shall reimburse Bank for all reasonable attorneys’ fees and all filing, recording, search, title insurance, appraisal, audit, and other reasonable costs incurred by Bank,
pursuant to, or in connection with, or relating to this Agreement (whether or not a lawsuit is filed), including, but not limited to, any reasonable attorneys’ fees and costs Bank incurs in order to do the following: prepare and negotiate this
Agreement and all present and future documents relating to this Agreement; obtain legal advice in connection with this Agreement or Borrower; enforce, or seek to enforce, any of its rights; prosecute actions against, or defend actions by, Account
Debtors; commence, intervene in, or defend any action or proceeding; initiate any complaint to be relieved of the automatic stay in bankruptcy; file or prosecute any probate claim, bankruptcy claim, third-party claim, or other claim; subject to any
limitations on fees specified elsewhere herein, examine, audit, copy, and inspect any of the Collateral or any of Borrower’s books and records; protect, obtain possession of, lease, dispose of, or otherwise enforce Bank’s security interest
in, the Collateral; and otherwise represent Bank in any litigation relating to Borrower. In satisfying Borrower’s obligation hereunder to reimburse Bank for attorneys fees, Borrower may, for convenience, issue checks directly to Bank’s
attorneys, Bingham McCutchen LLP, but Borrower acknowledges and agrees that Bingham McCutchen LLP is representing only Bank and not Borrower in connection with this Agreement. If either Bank or Borrower files any lawsuit against the other predicated
on a breach of this Agreement, the prevailing party in such action shall be entitled to recover its reasonable costs and attorneys’ fees, including (but not limited to) reasonable attorneys’ fees and 
  

 -28- 

 costs incurred in the enforcement of, execution upon or defense of any order, decree, award or judgment. All
attorneys’ fees and costs to which Bank may be entitled pursuant to this Section shall immediately become part of the Obligations, shall be due on demand and shall bear interest at a rate equal to the highest interest rate applicable to any of
the Obligations. 
  
 9.13 Benefit of Agreement. The
provisions of this Agreement shall be binding upon and inure to the benefit of the respective successors, assigns, heirs, beneficiaries and representatives of Borrower and Bank; provided, however, that Borrower may not assign or transfer any of its
rights under this Agreement without the prior written consent of Bank, and any prohibited assignment shall be void. No consent by Bank to any assignment shall release Borrower from its liability for the Obligations. 
  
 9.14 Limitation of Actions. Any claim or cause of action by
Borrower against Bank, its directors, officers, employees, agents, accountants or attorneys, based upon, arising from, or relating to this Agreement, or any other Loan Document, or any other transaction contemplated hereby or thereby or relating
hereto or thereto, or any other matter, cause or thing whatsoever, occurred, done, omitted or suffered to be done by Bank, its directors, officers, employees, agents, accountants or attorneys, shall be barred unless asserted by Borrower by the
commencement of an action or proceeding in a court of competent jurisdiction by the filing of a complaint within one year after the first act, occurrence or omission upon which such claim or cause of action, or any part thereof, is based, and the
service of a summons and complaint on an officer of Bank, or on any other person authorized to accept service on behalf of Bank, within thirty (30) days thereafter. Borrower agrees that such one-year period is a reasonable and sufficient time for
Borrower to investigate and act upon any such claim or cause of action. The one-year period provided herein shall not be waived, tolled, or extended except by the written consent of Bank in its sole discretion. This provision shall survive any
termination of this Agreement or any other Loan Document. 
  
 9.15 Paragraph Headings; Construction. Paragraph headings are only used in this Agreement for convenience. Borrower and Bank acknowledge that the headings may not describe completely the subject matter of the applicable
paragraph, and the headings shall not be used in any manner to construe, limit, define or interpret any term or provision of this Agreement. This Agreement has been fully reviewed and negotiated between the parties and no uncertainty or ambiguity in
any term or provision of this Agreement shall be construed strictly against Bank or Borrower under any rule of construction or otherwise. 
  
 9.16 Governing Law; Jurisdiction; Venue. This Agreement and all acts and transactions hereunder and all rights and obligations of Bank and
Borrower shall be governed by the laws of the State of California. As a material part of the consideration to Bank to enter into this Agreement, Borrower (a) agrees that all actions and proceedings relating directly or indirectly to this Agreement
shall, at Bank’s option, be litigated in courts located within California, and that the exclusive venue therefor shall be Santa Clara County; (b) consents to the jurisdiction and venue of any such court and consents to service of process in any
such action or proceeding by personal delivery or any other method permitted by law; and (c) waives any and all rights Borrower may have to object to the jurisdiction of any such court, or to transfer or change the venue of any such action or
proceeding.

 9.17 Mutual Waiver of Jury Trial. BORROWER AND BANK EACH HEREBY WAIVE THE RIGHT
TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER PRESENT OR FUTURE INSTRUMENT OR AGREEMENT BETWEEN BANK AND BORROWER, OR ANY CONDUCT, ACTS OR OMISSIONS OF BANK OR
BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH BANK OR BORROWER, IN ALL OF THE FOREGOING CASES, WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE. 
  
 9.18 Confidentiality. In handling any confidential
information of Borrower, Bank will exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (a) to Bank’s subsidiaries or affiliates in connection with their present or
prospective business relations with Borrower; (b) to prospective transferees or purchasers of any interest in the Loans which agree to maintain the confidentiality of such information pursuant to an agreement substantially similar to this Section
9.18; (c) as required by law, regulation, subpoena, or other order so long as Borrower is given notice thereof if practicable (and Bank is permitted to provide such notice) and an opportunity to seek a protective order, (d) as required in connection
with Bank’s examination or audit; and (e) as Bank considers appropriate in exercising remedies under this Agreement. Confidential information does not include information that either: (x) is in the public domain or in Bank’s possession
when disclosed to Bank, or becomes part of the public domain after disclosure to Bank; or (y) is disclosed to Bank by a third party and where, at the time of disclosure to Bank, Bank has no knowledge that such disclosure is wrongful or in violation

 So long as Borrower (1) maintains at all times with Bank unrestricted

The aggregate amount of the FX Forward Contracts at any one time may not exceed ten times the amount of the FX Reserve (which shall be in addition to other reserves). In the event at any time there are insufficient amounts available to Borrower for

 Re: Redback Networks, Inc. (the “Borrower”) 
  
 Ladies and Gentlemen: 
  
 Pursuant to the terms of a
Loan and Security Agreement between us and the Borrower dated March 10, 2004 (the “Loan Agreement”), we act as the lender for the Borrower and have been granted a security interest in all of its inventory and other personal property assets
(collectively, the “Collateral”). We understand that from time to time Collateral is delivered to you for storage, processing and/or other purposes. 
  

This letter constitutes notice to you of our security interest in the Collateral. Until you are notified to the contrary, however, you may continue to
accept instructions from the Borrower regarding the Collateral. 
  
 This will confirm your agreement that until such time as the obligations of the Borrower to us have been paid in full, you disclaim any liens on, claims to, or interest in the Collateral and the proceeds thereof and agree not to assert any
claim against the Collateral or proceeds thereof. You warrant to us that no negotiable warehouse receipts have been issued by you with respect to the Collateral, that you have not received notice from any other person claiming a security interest in
the Collateral, and that you will not, in the future issue any negotiable warehouse receipts with respect to the Collateral. 
  
 This will also confirm your agreement to (a) permit us, or our agent or representative, to enter upon the premises where the Collateral is located for the
purpose of exercising any right we may have under the terms of the Loan Agreement or otherwise, including, without limitation, the right to remove the Collateral; provided, however, that if we, or our agent or representative, in removing the
Collateral, damages any of your improvements on the premises, we will, at our expense, cause the same to be repaired, and (b) deliver the Collateral to us or as we direct (without cost to you), upon our written request. 
  
 To complete our records, kindly have a duplicate of this letter signed by an
officer of your company and return the same to us at your earliest convenience. You will note that this notification has been consented to by the Borrower. Please contact us at
                     with any questions. Thank you for your cooperation.
